She is almost 3 months old, buff orpington, she was dripping blood from her front feathers of her left wing. I brought her in washed her wing as much as she would let me. I sprayed it with bacon and fed her some snacks high in iron. She bled quite a bit when I brought her in and I could not find the source. We kept her inside for the night and it's been 2 days. Today I put her in the tub and sprayed her down and washed her wing with baby wash. It was hard and swollen about twice the size of the other one. Just the joint and it was warm. I put her back outside with the rest of the chickens. I fed them strawberries and she was not interested while the others were loving them. That was unlike her. Here are the pictures any help is greatly appreciated.
