I just got these chickens last week. I KNOW the one pullet did not have a bald butt when I got it or even yesterday.....for SURE not the day before. There are two pullets in there that are not even at POL. I just went out to check on them and the one has no feathers on her butt and it is swollen....not red, yet. What causes this and what do I do? I can't believe she would be egg bound as she has not started laying. I realize there is stress when you get them and I have been giving yogurt, BOSS and feed and keeping plenty of fresh water in the tractor. They are in quarantine and have been since I got them. This is a Cochin and she is around 6 months. Well here I am assuming she has not laid yet. But her face is not red, comb small.....assumed because she is a Cochin that she is like my rooster and slow to develop. Will have DH help when he gets home and get her out of the tractor and into a crate. She is eating. Looking healthy. Not lethargic at all. Came running for treats with the others. But between her legs and below her vent she is swollen and there are no feathers. The reason I know she had feathers when I got her is because two ended up being roos and two are hens. They were all butts towards me when I noticed. There were no bald butts. What could have happened so quickly? And what do do?
