I've been pretty lucky so far with my first every chickens. The chicks have all been healthy and active. No pasty butts or any other issues. However, I'm paranoid that my good luck will end one day and I'll need to treat some problem or another. My question for you all is, what sorts of things should I be keeping on hand in case something does go wrong? I'd like to have a chicken first aid kit already prepared and not be scrambling to the feed store in utter panic.
