So my 6 silkie chicks manage to mess up their bedding. I use newspaper for their brooder, and everyday I go out there to change it and its soaked through and sour smelling, and slimy. I've put up to ten layers of newspaper at a time, and it still gets soaked through. It's not the waterer that's leaking as far as I can tell because there's no drastic change in the water level overnight. What in the world are they doing? I used newspaper in the brooder for my other chicks and never had this problem. I don't know what's going on but it's gross. Any ideas?
