Hi Everyone! I'm new to BYC and chickens though have had horses for decades and goats for the last couple of years. Our first-ever chicks are due to arrive next week and we're working on their future chicken palace which is an 8x12 shed. The shed/coop is up on pier blocks, and I'm looking for input on whether to close off the area under the shed. The floor frame and supports are treated lumber which is the only viable choice for our rainy climate. Will chickens amuse themselves by pecking at the wood (again, treated lumber underneath) and get sick? Any suggestions would be much appreciated!
