I have a Buff Orpington hen that is 10 months old. Two weeks ago I noticed she was lame so I brought her in hoping her leg would heal. Unfortunately there seems to be no improvement. She walks on her hock. She has no noticeable injuries or ailments, other than she's limping. She had been eating and drinking great up until this weekend, however now she doesn't seem interested in her food. I've been giving her yogurt and she still likes sunflowers and scratch so I've been feeding her that. I'm quite certain she's lonely, but am hesitant to put her out with the rest of the birds in case she has something communicable. Any ideas? I've been reading a bit about Marek's but she's been this way for two weeks and doesn't seem to have any other symptoms.
