Update: I'm almost positive they have infectious coryza based on the smell of the mucous alone. I understand that even after treatment they will always be carriers, but seeing that these are the only two we plan on having, that doesn't bother me. I just want them to get better. I've been reading about various treatments, but I'm confused. It seems that the Sulfadimethoxine products say that it shouldn't be used on laying hens? Is this true? We definitely want to be able to consume the eggs when they do start laying What about the Marvel Aid (http://www.arcatapet.com/item.cfm?cat=808)? I've heard thses suggestions too: Streptomycin, sulphonamides, tylosin It would be great is anybody thats successfuly treated their chickens respond and let me know what worked. ______________________________________________________________________________________ Today we picked up two 6 month (or so they said) RIR's from a local feed store to put in the coop I just built for them. We picked them from a large coop with several dozen other hens, and chose two that appeared to be healthy and active (and almost all of them were), and overall we were pleased with the cleanliness and upkeep of the place. Got them home and gave them both a quick bath. I noticed that both of them seemed to have runny noses, with quite a bit of dried snot/food/dirt on their beaks. One even blew a small bubble when exhaling. The mucous is clearish white, and has a not-so great smell to it. I cleaned both of them up very carefully and we got them all settled. They both ate, drank and pooped just fine all afternoon. They both still had some leakage from their nostrils, but with everything cleaned it didn't seem to bad. Once it started getting dark they hopped in their coop (from the run) and when I last checked were fast asleep. Now, I've been reading post after post here...and it seems that this is nothing new. I did notice a few sneezes, but there is no labored breathing and no other symptoms that I can tell. I see some references to apple cider vinegar, yogurt and eggs. Is this a seperate option than antibiotics? Should I try and get some Tylan or LS-50 and give them that? We ( the whole family) are already attached to these sweet hens, so I want to make sure they get a clean start with us. I'd rather avoid the vet right now if there is something I can try on my own first. Thanks for any input you might have.
