Big problems today. Chirpy, finally started to be quiet last night and I checked on her now and again and she always seemed to be sleeping or mid-sleep while standing. I figured she wore herself out crying and was finally settling down. This morning I check on them and she is still one that seems to be sleepier than the others. I hadn't seen her eat or sleep recently. I did my morning pasty butt check and everyone seems fine, including Chirpy...so I go to sit and have breakfast. Suddenly I hear Chirpy again, crying out as she does. I was happy and go to check on her but I found her on her back with her feet in the air, being run over by the other chicks.
Just to be safe I isolated her. I got her into a separate box that is still in the main brooder and she cried a bunch, walked around a bit and poked at the food dish in there...she seemed ok. Chickens do strange things. From much forum reading I've learned a lot about people freaking out about things their chickens do and lying on their backs with feet in the air isn't too terribly unusual. I let her be and went to eat again and heard her cry again, so I went to check...again she was on her side and looked like she was having trouble breathing.
I picked her up in my hand and turned her over, thinking maybe she was choking or something. I rubbed her crop and belly but she went limp, struggling to breathe. Her vent looked fine, no poop, no blood, belly button fine I suppose, but she has basically suddenly gone limp now and I don't know what to do next.
