I've just rescued by hen from a dog who roughed her up pretty well: she now has a big bald spot on her back with a puncture wounds and an area where the skin is torn away. I've sprayed it with Vetricin and she is isolated. Here are my questions: What else can I do to help her? How can I cover the bald spot, both to protect her from the other girls ,and to keep her warm this winter? We live in MA.
