EE with runny nose, smelly discharge, lice, Infectious Coryza??

Hi everyone, I am a newer chicken owner, and I have a sick chicken. About a month ago I brought home a BC Marans who is now 5 months old from someone on Craigslist. I kept the birds seperated for about a week (yes I know I should have done it much longer) and during that time I didn't notice anything wrong with the Marans. On the second week, there were two days that I noticed snot bubbles on the Marans but didn't think much of it, she is a messy eater and I figured it was related to that. It only lasted two days, and she no longer has a runny nose. At this time I started adding the Rooster Booster to their feed to help with any stress the new bird may be causing.
Over the past month of having this new bird, I've kept a close eye on her and my other birds (1 EE, 3 silkies, all 4 months old now), checking for anything that doesn't belong, I've probably checked her over a dozen times. This past week I saw what I think were lice on the Marans, and one other bird. Everyone got baths, and dusted with Prozap Insectrin Dust - Permethrin. There is now no sign of lice. Also this past week, my EE has started to have a runny nose. I think it started off clear and it is now a very light yellow. It has an odor, possibly sour smelly, I wouldn't compare it to puss. Everyone has still been getting the food with rooster booster mixed in, but I have been giving my EE 2cc of the rooster booster daily to make sure she is getting enough. The days I give it, there seems to be less nasal discharge the next day.
Last night I was searching all over to try to figure out what might be causing the runny nose. Now I've got myself all worried and convined that they've got Infectious Coryza. So what do I do now? I've got 5 birds total, 3 show no symptoms at all, 1 did for a while, and the EE does currently. Should I keep trying to treat it at home? With what? Is it time for a vet? I'm really worried and feel like I've really screwed up by bringing home this bird from Craigslist.

Here is a little more info:
1) What type of bird , age and weight: Easter Egger mutt from feedstore, 4 months old

2) What is the behavior, exactly: Runny nose with an odor, she acts totally normal, runs everywhere she goes, very active. After I open her mouth her breathing sounds stuffy, but I don't know if it is from me accidently choking her while opening her mouth or something.

3) Is there any bleeding, injury, broken bones or other sign of trauma: no

4) What happened, if anything that you know of, that may have caused the situation: Introduced new chicken aprox 1 month ago.

5) What has the bird been eating and drinking, if at all: I feed an organic starter feed (don't know the brand, comes in a purple/blue bag I believe), oatmeal, yogurt, banana, tomatoes, scrambled eggs, they freerange in my fenced yard all day. Drinking is normal.

6) How does the poop look? Normal? Bloody? Runny? etc. Normal.

7) What has been the treatment you have administered so far? For the past 2 weeks, I've been mixing in this: http://www.roosterboosterproducts.com/product/50401 with their food to help with the stress of having the new chicken. It is rooster booster poultry cell. I've given it directly to my sick EE a couple of times and she seems to have a slightly less runny nose the next day, but hasn't gone away.

8 ) What is your intent as far as treatment? For example, do you want to treat completely yourself, or do you need help in stabilizing the bird til you can get to a vet? Either one, I'd like to try treating at home first, I'd just like someone elses opinion and what they would do if they were in my shoes.

9) If you have a picture of the wound or condition, please post it. It may help.

10) Describe the housing/bedding in use: I was using the pellets until this last week, then I switched to white shavings. They have an A-frame chicken tractor, that I clean out weekly, and use lots of DE.

Here are some pictures, her nose doesn't look that bad today, but it still has crusties on it:






and my disease carrier:

I am not sure it is Coryza, but here's some recommendations for treating and preventing.

One a bird gets it, I believe they are always a carrier.

TREATMENT AND CONTROL:

Flock medication with a sulfonamide or antibiotic is recommended. Various sulfonamides -- sulfadimethoxine (SDM), sulfaqumnline (SQ), sulfamet hazine (sulmet) are all effective; however, sulfadimethoxine is the safest and the one prescribed as treatment of choice. SQ and Sulmet are more toxic and require intermittent administration. Therapy in the drinking water will give more immediate response and reduce the severity of the disease. Feed administration of the sulfa or antibiotic does extend the period of treatment for better control. A combination treatment approach is advisable. Administer medication in the drinking water until medicated feed can be provided. Antibiotics that are beneficial include tetracycline, erythromycin, spectihomycin and tylosin. All are safe and approved for use in poultry. Control cannot be accomplished with drugs alone. Management is equally important. A bacterin is available that can be used in a control or eradication program. The bacterin requires multiple injections to be effective which makes it costly and cumbersome for commercial flocks. Control requires attention to flock sanitation, biosecurity, preventive medication, clean and sanitary premises, and disease-free replacements.

PREVENTION:

Prevention requires eradication of the disease (depopulation if necessary), good husbandry, strict biosecurity, all in-all out program, raise own breeder replacement, and do not mix ages or species. Most outbreaks occur as a result of mixing flocks. If you have an outbreak, segregate birds by age, etc., properly dispose of dead birds, medicate to stop the spread of the disease and initiate eradication procedures. Do not save recovered birds for breeder replacements. Premises should be vacant for 30 to 60 days after cleaning and disinfecting before repopulating or onset of the new season. Breeders should be replaced from a Coryza-clean source.

PM threehorses, she is so very smart when it comes to poultry!

Thank you for the info, I'm really hoping it isn't the Coryza, and is maybe just a basic respitory infection or something...

Hopefully, someone will come along and help you out that has experienced this first hand.

I sure hope so, I need suggestions for what to try next!

I have a pullet with a very small amount of nasal discharge as well - it's been like that for a few weeks now. They've all been treated with a wide spectrum anti-biotic but this poor girls' beak just always has a bit of goo on that one spot.
I am curious to see recommendations as well!

I had this same problem when I brought home 2 cochin hens from the flea market. After a few days I noticed that they were sneezing, had runny noses, and smelled sour. I gave them Tylan 50 injections for a week...nothing happened. They seemed fine other than the occasional sneeze and runny nose, so I put them back with the flock. I was faced with culling them or putting them with the flock. I chose to give them a chance. It has been about 3 weeks now and every now and then I hear a few sneezes from the flock (mainly the cochins) and a few of them have crusty noses. Nothing too serious. I may have done the wrong thing by putting them with the flock, but I did what I thought was right at the time.

Good luck!

That's pretty much my situation as well. I don't show my birds or hatch, they're mostly kept as pets, and since other than the occasional sneezing and discharge from the one hen (she's a Cochin, as well....) AND since they free range and are apt to be picking up lord knows what from the wild bird population around here, well.....what else can you do, right? They are happy and healthy otherwise, so......

well, I'm glad to hear I'm not the only one with this sort of issue. From what I've been reading online, it says that although the Coryza will eventually spread to all the birds, it really isn't THAT harmful to them? I've also seen posts here on BYC though where people say you must cull the entire flock? I've only got 5 total and I've become very attached to all of them, so if they need an extra boost every so often I'm willing to give it a shot. I've never used Tylan before, and I've never injected anything before... I'm assuming you can get it at a feed store? Is it easy to inject?

anyone else have suggestions on what to do next?
