I have 7 RIR Hens. They have been laying since last October. Today I noticed one was missing. My kids found her under a bush. It looks like something has attacked her and I think her wing is broken. Do I clean her wounds with warm water only or is there something I can put on it? Does this look like a dog attack? The open wound, which my daughter is pointing to, is an open circle. The skin is actually torn and she has air pockets on the opposite side. Does her wing "look" broke to anyone? She will not move it but she lets me fan it out. We put her in a cage with food, water, and straw for bedding. She is eating and drinking. We also found another of our girls (RIR) that looks like something grabbed her on the bottom as she is missing feathers just under her vent although there are no puncture wounds. These are the first hens we bought as chicks and even though we get eggs from them they are more like pets. I feel so bad for them. Thanks for any advice.
