Like others said, I'm glad she has you. If she is getting along fine, eating and not suffering, I think she will have a very nice life with you. She does remind me of a Kiwi bird.
As soon as you started talking about her head and an abscess, I knew it was THE Sugar!!! YAY!!! I have been wondering about the two of you and now I have my answer. So glad to see her oding so well. She is a special chicken indeed and I don't mean genetically.
