I foster dogs for a rescue group. Brought one home today and didn't realize the gate separateing the side and back yard was open. The hens were roaming in back and the dog went after them. One got nabbed by the rump and has a puncture wound on the top of her tail area. No blood loss. She let me handle her so I rinsed it with peroxide and have put her in a cage by herself. She would not drink from a bowl so I dripped water on her beak with a syringe and she took it. What do I do now? Does a wound need stitches or will it heal? Does she need medication? My other hens are flighty now and I keep chasing them back into the yard. If these keeps up I'm get my XXL crate and putting them all in there. FYI - 15 weeks old approx. now.
