Howdy. So this is week 2 of having our chicks outside in the coop. Our coop is from TSC and we used pressure treated 2x6s for flooring to prevent digging predators from coming in. However, in cleaning the flooring weekly we are seeing that after hosing and pushing out the coop, the dirty water does not drain quickly. I clean it while the chicks free range, and so far have only the wood as flooring. I'm curious in what methods folks are using for efficient drainage while still keeping out predators. Also, I just read up on using river sand for flooring, would this be far better and more sanitary than keeping the bare wood and pressure washing??
