I used to be an EMT, Medical Assistant, and Vet Assistant. (yeah, I get around). So that helped with a lot of the basic stuff. But since owning chickens, and there are no vets in the area that will treat chickens, when there's an injury to them, you have to patch them up yourself. I've even performed minor surgery on them at home. So far...all are survivors! Next...my family members...muahahahahaha.
