I have a 2-3 year old hen, red sex link, nothing special. I nticed ehr bedded down in the coop last night and checked under her for eggs, and when I found nothing, I just assumed she was keeping her feet warm. This morning, she wouln't leave the coop. She can barely stand on her own. I checked ehr butt and found a pasty white mess, so I assumed coccidosis. I started syringe-feeding her water with corid in it, which seemed to perk her up.... Until a few minutes later, when she leaned her head forward and vomited. Her breathing is wheezy, and when I femt her rear to check for ascities, I felt a hard mass. When I squeezed the mass, very red tissue (at this point I was thinking prolapse) started emerging from the vent. Some liquid and feces came out, but the hen started kicking and appeared to be in pin, so I stopped squeezing and left her. She just lays there, barely keeping ehr eyes open. I'm not sure what this is- it's not sour crop, not coccidosis... any ideas? At this point I'm thinking an internal prolapsed uterus. My thoughts are maybe squeezing it out, rinsing with warm soap and water, and carefully putting it back in. But I have no clue what is causing this. I've dealt with soure crop, bumblefoot, and coccidosis, but not something like this. Does anyone have any idea what this is? She's so listless I'm considering putting her down, but would like to hear if anyone has any experience with this first.
