So I’ve had a couple flocks of seramas for 3 years now. Because I had one perish overnight when the temperature dipped just under 40 degrees F suddenly one night, after much deliberation I decided to put in their coop supplemental heating via heat mats. These are the kind used for dogs and cats. You plug them into the outlet and they just give off a gentle warmth, have a hard plastic shell. The chickens sit on top of it and it keeps their feet, tummies and chests warm. This has worked very well for them these past years. It also kept the roosters from getting frostbite on their combs. They seem very contented to have a warm snuggly bed to sleep on during these cold nights. I haven’t had a problem...until....

Early this year I noticed large holes in the walls of my coop: RATS. :mad::barnie I put up hardware cloth everywhere and started trapping, made sure excess food was picked up...etc. I thankfully was able to “un-rat” my coop to such an extent that in most of my chicken pens inside this coop (it’s basically a large outbuilding/shed) there was no evidence they were present or had the possibility of getting in. But you know how it is with varmints... once they find a place they like they’ll keep on trying. And yes, I both saw and found evidence of them yet again, particularly only in the one section of my coop where the one electrical outlet is. The very same outlet I use to plug in all my heat mats. :(. In fact, that ‘evidence’ was that the rat had chewed straight through a heavy duty extension cord that I use for my heat mat. It wasn’t plugged in at the time, but of course this has me concerned as to how to handle this.

I’m almost afraid to ask, but what could occur if a rat attempted to chew through one of these electrical cords while they are plugged in? I use the deep litter method method- pine chips- in the winter. I do try to put the cords up off the floor but sometimes a chicken (serama) will try and perch on it and bring it down. My fears are the rat could chew the cord, get zapped, and start a fire. All the heat mats are on raised platforms high off (about 3 to 4 feet) the bedding and the extension cords I put up along near the ceiling and try to make it so that the cord is taught(ish) to the outlet...kind of more like a laundry line to the outlet. But this isn’t too far off the floor and I still still reachable in areas that rats could get to. If the rat chewed the cord and disrupted the current, could my chickens sleeping on the heat mat get electrocuted as well? :confused: It’s probably silly of me to have assumed I only had rats in my coop earlier this year and not at all in the past 9ish years I’ve had the coop. I probably even had them in the coop when I used my heat mats before but just was oblivious to them being there and the potential danger.

Do rats and mice sort of know not to chew on live electrical wires? And do varmints chewing on wires create fires?! And how is it that in old houses (or even new ones) that houses are protected from fires and rats chewing on, say, live electrical wires in the attics, walls or crawl spaces where they usually reside? Is there anything I can do to protect the extension cords from getting chewed? Any protective products? Are there such things as fire alarms for barns that will only sound inside your house, as if by remote, notifying you, but not sounding off in the barn (scaring the animals half to death even if it was a false alarm)?

Should I be concerned, if so how much? Is this potentially dangerous? I both want to avoid having to continually buy replacement expensive extension cords AND avoid fires/electric shock to myself or chickens. There’s one more adjustment I can make to my coop to prevent the rats getting into this section of the coop, which I plan to tackle tomorrow, but even after those alterations, there’s no promising a rat-free coop...anywhere at anytime....I know those darn suckers will try their best. And so, knowing that, I need some advice and knowledge regarding the use heat mats, and electrical cords in a coop that now not only houses a few flocks of chickens but destructive rats. :he

Anyone offer some safety tips? Advice? Remember, these are Seramas I’m giving supplemental heating to, not my regular flock which I know will be fine in these cooler temps. Night time temps dip below freezing this week. I’ve got the heat mats on this evening...can’t sleep because I’m worried about my babies and crossing my fingers :fl.

Thanks in advance.
 
You do have a lot of questions,,, so let me address a few.
Switch your extension cord to one of these, and just put proper ends on cable.

The electrical department person can assist you to get correct plug, and outlet for your use.

Because I had one perish overnight when the temperature dipped just under 40 degrees F suddenly one night, after much deliberation I decided to put in their coop supplemental heating via heat mats.

I have Seramas,,, and I would be hesitant to agree that at that temperature,,,,, 40*F was cause of death.
I am not against providing HEAT for Seramas.

Do rats and mice sort of know not to chew on live electrical wires? And do varmints chewing on wires create fires?!

Rodents chew on the plastic insulation, exposing the wires. They think the plastic is nutrition. The fire hazard occurs when wires are exposed, and a short occurs. It does not always happen, but potentially can, so best to avoid bare open wires for safety regardless.
Squirrels have been eating the plastic on my lawnmower fuel tanks, as well as gasoline plastic cans, and Rubbermaid 32 gallon yard trash can lids. I smeared the lawnmower fuel tanks with some Automotive grease, and seemed to stop that activity. Maybe if you would coat the plastic extension cord with some grease, and wiped it but not totally wiped off, it may make extension cord less desirable to chewing.:idunno

There’s one more adjustment I can make to my coop to prevent the rats getting into this section of the coop, which I plan to tackle tomorrow, but even after those alterations, there’s no promising a rat-free

Prevention of rats is key,,, Try your best. Maybe even consider making a Raccoon lunch box. (a rat trap inside a wooden box with a round access opening). Keeps your chickens safe from snap action.

WISHING YOU BEST,,,,,,,,,,,,,,,,,,,,,,,,,, :highfive:
 
So help me, i find one rat in my house this year, im gonna end up being legally insane and start trilling and cooing like my babies do. On a good note, i have a pit that likes to chase things smaller then her... and two cats. And i already checked my stock of great stuff foam/steel wool for just incase.

Sorry though, i have no advice but think the one above about the steel cord is a great idea.
 
Do what you want, but your birds don't need it. The death of your one bird was from something else, not temperature.

I have always been a "No electric in the coop" kinda guy. Supplemental lighting has always been battery. Water heater outside of the coop.

With that said, I run extension cords to the barn for the water heaters in the winter. I've never had a problem with rats or mice chewing them. Only problem has been the GFI receptacle the extension cords are plugged into likes to trip. I'm not saying this is the outcome for everyone.

So be smart and use a GFI to plug into. Check the cords daily. A cut extension cord from driving over it or a mouse chewing it, isn't going to automatically cause a fire.
 
All good advice!
Only poison in safe bait stations will eliminate a rat infestation, besides rodent proofing your coops. Both need to happen.
Our barn and coop are wired in conduit and/ or that metal covered electric cable, and with GFI outlets, and everything that our licensed electrician could think to add. Covered outdoor rated outlet boxes, everything.
If anything burns down, it won't be because we didn't try for safety!

Wow! Really great comments and advice! Thank you all!


I have a few more questions tho- what are GFI outlets?

What is “safe bait” poison? We have stray cats who regularly catch and eat the rats. I would hate for them or one of my free ranging chickens to eat a poisoned rat carcass then die. I agree baited poison is great and works wonderfully, but it doesn’t seem like a good option if you’ve got other animals around. I’m not sure what safe bait is. Perhaps this is something different.

Absolutely love the metal coiled extension cord idea. Thank you- had no idea this existed! Those are the type of cords that come with the heat mats- only they are not long enough to reach the outlets. They have never had chew marks. A rat could still try and sink it’s teeth into it, but it looks like it wouldn’t have a good time at it, cumbersome not-worth-the-effort-chew. Would I have to worry about length of cord/voltage/wattage with these? I’d have no idea how to rig these up with male and female ends, but I might call up an electrician soon to help with that and another job on the to-do list.

I’m not sure what electrical conduit is...will look it up.

I have thought about using pvc pipe, but it seems to me, getting it tight enough so that the rat couldn’t wander in to chew and getting the plug end to slip through -depending on size, could be tricky. I don’t know also how to affix this to the outlet, or safely.


Oh and yes, I wasn’t sure that the cooler temp killed my serama. She had been perfectly fine and was just gone the next morning. It was one of those freakish days where the weather had been Indian summer days and nights, then straight away dropped 30 degrees at night. Anyway, I just didn’t want to take any chances of more loss. I heard some are more cold tolerant than others. I got my flock from Louisiana, so I just assumed these were birds not accustomed at all for the weather we have up here. Last winter we had temps below zero for a couple weeks. They did ok. I didn’t tho! :thI have heard they should be fine, but I want to keep them healthy and also trying to save the serama roo’s combs from frostbite.
 
Most, but not all, dying rodents will return to their tunnels and die there, unavailable to most other predators. Rats will also spread diseases that we can all get, and kill chickens. They are NOT only going to eat some feed!!!
Hire/ consult a licensed electrician!! It's too important to mess this all up, and if you watch an expert, you will learn how to do it in the future.
Our farm insurance company cared too...
