I have a chick thats about 4 weeks old. The only chick that has had pasty butt. I clean his butt frequently. Today when I got off work, I noticed it looked like he had a prolapsed vent. Some clearing liquid was coming from his red very swollen bottom. I submerged his body in warm water. Washed off the whitish colored stuck on poop,and tried to massage his bottom area (not the vent portion) and I stuck him in the incubator away from the other chicks. I also put a barrier protectant on his red inflamed vent. And let him be. About 20 minutes later I came to check on him. And there was a poop about an inch long, and a little smaller diameter of a pencil in the incubator with him. He still looks to be pushing and struggling. Any suggestions on how I can help this baby?
