We just got her about 2 weeks ago and haven't added any since. I haven't seen any other of the symptoms you mentioned. She hasn't laid an egg since I isolated her. Thanks for answering.
Can someone please help? I have a hen with a swollen eye. She's not eating or drinking well, is very lethargic, and has lost a ton of feathers on her belly (I think from laying on her tummy a lot). She is an Azure if that helps.
