Hi everyone. New chicken mama here seeking insight. I have a 9 mo hen who I noticed yesterday has missing feathers on her neck. Her skin doesn't appear injured or raw just naked. I have 6 other birds besides her and everyone else seems fine, no feather loss. I'm also having some issues with her crop not emptying completely at night. She seems to have a slow crop but is eating and drinking fine, laying and has lots of energy. I massage her crop several times a day. But this is probably an issue for another post. I'm just wondering if there might be a connection. Any input would be welcome!
