Is it ok to use NO bedding at all? I have 1 week old meat chicks in a HUGE cardboard box. I have four thick flannel-backed plastic tablecloths that I want to use as liners in the box. I want to change them every morning and night. I want to take the dirty one outside and spray it and sunshine clothesline dry it so it will be ready to reuse the next day. I have already went through all the puppy pads and shaved wood animal bedding that I bought in just 1 week. They are dirtying a lot worse now and I want it really clean but as inexpensively as possible. Not to mention the tablecloths are cute also.
