My 2 chicks are almost 2 weeks old. They've been in a plastic bin brooder. I'm still only using paper towels on the bottom. With only 2 of them, it lasts a long time - the poo dries quickly, and it doesn't smell at all. I want my chicks to have more room to run around, so I'm thinking of making a bigger brooder in my basement out of 2 cardboard boxes (open underneath) taped together to make an octagon shape. I have window screens to put over the top. My question is, is it practical to use sand in the bottom? I will put a shower curtain on the floor, then newspapers. The idea of pine shavings scares me, as I've read about chicks eating them. But would sand work well? How deep would it have to be? Remember, we're only talking about 2 chicks, so maybe not all that deep? I could keep it scooped out, and then use it in the outdoor run, couldn't I? Also, what kind of sand, sandbox or construction?
