I have a two year old Amerauana hen that has been sort of moping around and off her feed for a couple of days. I just found that she has a large, very hard lump, well, in her back end for lack of a better way to phrase it. It is right where the egg would be sitting if she was getting ready to lay it, but there is either a lot of inflammation around it or that is one HUGE egg, because I don't think there is any way she could pass something the size of what I am feeling back there. She is also very thin, and I am betting dehydrated because her skin looks very dry. I have done sub-q fluids for dehydrated cats/furry creatures before, but I have no idea how to do it for a chicken, or if that is appropriate in this case or not. Can anyone give me any advice on how to help her?
