I noticed one of my pekin hens has a swollen belly this morning. I haven't tried to catch her yet but i took a lot of pictures. She's not really standing any differnt to her sisters but she is a little slower than them. Besides the swollen belly she seems happy but i know birds are good at hiding their symptoms and stress. We had one hen that was going broody but I'm not sure if it was her. I haven't really found anything online for diagnosing them or treating them. Is it just the same as treating chickens?
