I would appreciate any help you chicken lovers can give. I have a 3 year old Langshan chicken who is still healthy, but has a soft, enlarged spot on her chest the size of a baseball. The feathers are falling off the spot. She seems fine otherwise- she has always been quiet. She is eating and drinking just fine. Does anyone know what this is? Should I be taking her to an avian vet, and if so, is anyone familiar with one in the Fort Worth area? (The area on the chest is to the right of center, and is actually midway between her neck and her legs. It does not appear to bother her when we gently press on it, but she is not a very expressive chicken anyway. She has always been very passive). Thank you so much!!
