We received our babies this morning from the hatchery. I had put pine shaving in the brooder as litter but then someone said not to use them until the chicks were a week old because they would eat it. I put a sheet down on top of it and they are ok with that except that it's getting dirty fast. If they are eating well can I take the sheet up and see how they do. We did put some green beans and grass in for them to peck at. What do you think?
