Hello! My chicks are coming in very soon, which is exciting, and I'm setting up the brooder, I just have a few questions...as I've never used an unused bathtub before. lol What would be safe to line it with? Would garbage bags be OK, or would they potentially be able to ingest some if they scratched enough? Or would it be better to just do a layer of pine shavings over the tub floor? Apologies for all of the questions!!
