I have an OEG / Showgirl mix that I have had since she hatched. She is about 4-5 months old. About 3 weeks ago she started limping. Then that foot started to curl and she was walking on it like that. Then about 2 weeks ago I found her on her back trying to get up. So I have had her in isolation for the last two weeks. Both her legs now seem to not be working right. She tends to push them both back and wont sit on them right. She will sit when i place her right and will eat and drink then but when she tries to move she just spins around or just kicks. She looks good in her eyes, her comb has good color, no raspy, no bubbles, everything seems fine except her legs. I gave her tetracyclene for one week, then sulmet for 4 days, and have been giving her poly-visol (no iron) for about 5 days. I do not know what else to do for her or what it could be. No other chickens are showing any signs of the same illness Edited.... I dont think its Mareks, but I am not really sure. She has been in a cage in the coop with the other chickens (like a parrot cage type thing on the ground. Any help would be great! Thank you!!
