Have you seen any droppings passed that look like 'regular' droppings, though maybe abnormal? Like yellow or green or watery droppings? Or are all of them like this? Sometimes reproductive problems can have odd or varying symptoms that can be hard to know for sure until necropsy. And they...
How old is your chick? Is it acting normally otherwise, or is it acting sick or lethargic? Is it eating and drinking normally? Do you have a picture of the dropping you saw? Pictures are often helpful.
I also semi free range during daylight hours. I have a very large fenced area that they can range in. I have 40 birds and it still has grass over 80% of it, so it's definitely large enough. And I have Fayoumi's who are digging demons, so a lot is dug up. Mine have to be fenced due to roaming...
Do you know when she last laid?
My first reaction was kidney issues, that could cause excessive water intake and diarrhea or very runny droppings. Without blood work that would be hard to rule in or out. Despite the weight loss does her abdomen feel bloated at all? A blockage or partial...
If they have just started laying, and you don't have adequate nest boxes for them, that could be a cause of spats. It's not uncommon for a hen to get pecked and bullied by someone else that wants the box she's in.
As others have said, at 7 years old coccidiosis is less likely. But not impossible. Corid is very safe and it won't hurt her if you want to try and see if it helps. It is not an antibiotic, it just stops coccidia from being able to metabolize thiamine (which is what they feed on) so they die...
There are many brands of Flock Raiser or All Flock type feeds. If you cannot find those then any starter/grower feed in the 18% protein range is fine as well. That is what I buy when I can't find an all flock feed in stock. Most commercial feeds are made to be well balanced, you can further...
In addition to the possible nutritional issues, it's more likely that a roo would be getting broken/fractured toes. They are heavier, so the additional weight puts more stress on those small bones, which might be weakened by deficiency. When they heal wonky, they usually can't be corrected...
They are basically the same thing, gatorade might be higher in sugar. It may help to put rolled up bath towels around her to help her stay upright, kind of like a nest. Some birds will relax that way and be more comfortable. If it freaks her out and she struggles to get out, then leave them...
If you have a vet that sees chickens, that is a good option since there are several possible causes. Respiratory diseases like infectious Coryza and Mycoplasma Galisepticum are not uncommon and can cause mucous and bad smell, facial swelling, MG can cause foamy bubbles in the eyes. If you want...
I don't think B12 is going to be helpful, C isn't either.
Do you have calcium? Even tums can help in an emergency. If nothing else I would give her warmed fluids, pedialite, gatorade, home made electrolites, get her as hydrated as you can. For homemade electrolites : 1 cup water, 2 tsp...
You need a b complex that contains all the b's, riboflavin (B2) and thiamine (B1) being the most important ones. If you have any Poultry Cell, it contains both.
If you think she's having trouble passing an egg, then the epsom salt soak can help, also give her calcium (calcium citrate +D is best absorbed, Citracal or generic equivalent), 600-800 mg once a day. That will help with contractions to help her pass anything. Just like the B, you can put it...

Has she possibly had access to anything toxic? Fluids leaking from vehicles, pesticides, anything rotting or spoiled, moldy feed, etc? If you think that may be the case then activated charcoal can help for organic toxins. It's very dehydrating so you have to give a lot of fluids as well. If...
If you haven't had a fecal test done, before and after treating with those things, then you have no way to know if you are actually successfully treating anything. Or not. Most parasites will never be visible. I had some very sick birds, and lost a few to secondary infections from heavy loads...
DE is ineffective for internal parasites. Corid is only effective for coccidiosis. For tapeworm Equimax or Zimectrin Gold are the meds to use, Equimax is more economical, but if you can't find it then you can use the Zimectrin Gold.
Safeguard will treat all types except tapeworm. If you don't know what type of worm you are treating for then Safeguard dose is .23 ml per pound of body weight, once a day, 5 days in a row. If you KNOW you are only treating for roundworm then you can do two doses 10 days apart. That will only...
Some hens will do that. A roo will take over and be the dominant one, if no roo then often a dominant hen plays the part. I had one hen that was just totally obnoxious without a roo in the flock. I lost one and was without for a period of time. Once I relplaced him, she calmed down and was...
