Hello! My.... uh..... 3 year old EE, who looks JUST like the one in the above picture, seems to have a bit of an issue. Her butt is missing a few feathers, probably from the normal pecking order, and there are still stumps from her last molt. She is ALL the way at the bottom of my 3-chicken pecking order. She is completely like the other 2 hens- walks normal, sleeps normal, eats and drinks, no problems breathing, etc. Basucally ALL the isgns of a healthy chicken. The only thing is, she seems to be a bit fatter, if that helps, and her butt is a bit swollen. The swollen place is about an inch below her vent, and looks like this: So, yeah.... what is wrong with her?
