Why do you use wood ash? Like what exactly is it supposed to do *we had a lot of rain. 3 of 16 coops got partly flooded. I threw some wood ash over mud. luckily I have ducks there. I'll ask a couple of friends to collect ash from their stoves to put more then I'll put sand in the lower part of the coops. they are sloped so I hope when I level them they will not flood again.
Wood ash and water can be highly alkaline and burn skin, I never thought about putting it in a wet coop. You've never burned your animals?
