So I have about 20 chickens total, all within the age of 2-4 months. I just bought 3 silkies from a friend and they are about 2 months old, living outside. Today, my neighbors puppy accidentally got ahold of one of my silkies. I'm absolutely devistated. Her whole front/chest is open. No skin or anything, you can see both of her breasts. It's about a 2 and a 1/2 inch gap with no skin what so ever. The breasts aren't bleeding and don't have holes in them, it's just like her skin was torn/ripped off. So far, I put her in a large box inside alone with food and water, and a soft towel. She was cherping a lot from being alone so I brought the 2 silkies in that I bought with her. She seems much happier now, she's laying in between them and they don't pick at her at all. They seem to almost snuggle with her and protect her. She's walking find and acting okay but the wound looks very bad. What should I do? Treatment or just not touch it at all?
