Hello, I have recently bought two peking bantams and maran... they are all getting on fine and are healthy except I have noticed that my youngest peking has..well...a pulsating bottom? She doesn't have as much of a fluffy bottom as the the other peking, so I just wondered if this was normal, and just a bit more on show because of lacking feathers orrr she is egg bound or has some other ailment. She seems happy enough, but isn't laying like my other one. I've tried having a look but can't see anything too stuck. Please could someone shed some light! Thanks!!
