I have a bird named Jesse. Last night I found her in the corner of the coop puffed out tail down walking funny I thought egg bound since it was hatched in march no idea if pullets or cockerl I brought it in have it under heat lamp with yougert water in a towel this morning she can't stand up. I put her on her feet she fell forward and couldn't get up. I am at a loss. Is this cocci merks she sounds raspy. Heavy breathing almost gasping. Coughing. But no runny nose or eyes. She won't eat but I am getting her to drink with a dropper. I have 16 other chickens outside. One hatched with her plus 6 pullets from tsc. And 2 and 3year old hens my original flock. Plus 8 in the brooder. Please tell me I am not going to have to cull my endtire flock I would be crushed.
