PLEASE HELP! Ok...so I have had quite a time with these chickens. All brought in new end of September. they were born in June and shipped and raised in horse stall sheds in a barn and I bought them there. Ok. so a few had some sneezing. Thought cold. Then, found a GIANT roundworm in poop. Went to these boards. Wormed them per directions with fenbenzadole (Safeguard) after called the manufacterer for specific amounts. Also, the new rooster that I had brought in was breathing very loudly only through his mouth (he has gotten somewhat better with the antis). During this worming time or immediately following the worming, a different rooster and a hen (both Buff orpingtons) developed significant drool/spit in their mouths. The hen could be heard with rattles in her chest when she would breath, etc. Also, and this is my main question, but may be part of the whole thing, I dont' know, the rooster and the hen developed bright red between their toes and starting up the backs of their legs. Not raised or scaley or anything, just looks like between their toes is bright red and going up the back of their legs like a big stripe. I immediately gave them all a 5-day course of duramycin 50 (tetracyline) in their water to try to help with what is thought to be a respiratory infection/virus. This ended yesterday night. Now, the other rooster that was the one that seemed sick to begin with and got better is developing this red bright skin between his toes. HELP! My poor chickens! They were supposed to be "very healthy!". What up?
