One of my chickens has had rather straggly feathers for a while, just thought she may be going through a late moult.
I picked her up this eveing, haven't done for a while and she has lost lots of weight. There is nothing to her, just bones. :( She seems to eat when I see her.
Any ideas what may be wrong with her. I've wormed recently, but might it be that? She is about 4 years old.
