I am setting up a first aid kit for my birds. Similer to what I had for my horses but I was wondering about a product called underwoods horse medicine. I used it for my horses when I had them and it can be fairly hard to find around here but it worked wonders for major and minor wounds. Is this safe to use for chickens? I know it works like a miracle drug. I can not remember what it had in it just know it took a life threatening wound on my horse and saved his life.
