I think I've got a sick chicken. Some quick background, this chicken literally wandered into my backyard, in urban auckland a year ago and didn't leave. I don't know what type she is but I think maybe a brown shaver as she looks like some but not all photos of that breed, and I obviously have no idea how old she is. She has been giving us an egg each day and has been sleeping in a chicken coop with a small run which we bought her. She has a friend now, a Rhode Island Red, and they have been cohabitating for just under a year. I've been feeding her poultry pellets from pack n save. I've no idea where else to get food from.
The problem....
I haven't had any eggs from her the last few days, then today I noticed she was limping and holding one leg up. Tonight I went out and had a good look. No sign of red mites. She is missing all feathers around her comb (the red sticky uppy bit at the top of her head, yes I'm a newbie) on her tummy the skin is all red looking and the feathers are broken off, the quill is still attached. I think she has scaly leg mite as well, I've tried to treat this in the past with dipping in canola oil for days in a row with no success. I noticed on the sore foot that on the top, outer, of the foot are a red area, like a spot. The skin is not broken, and there is one spot each side.
Obviously it's not a healthy chicky, where do I start? I really haven't a clue what I'm doing here when it comes to sickness. Please help.
