I have had my chicks for a few hours now, and the puppy pads are already disgusting and covered in poo. I need another bedding option. I know that I can change them, and planned to a few times a day, but it only takes a couple of hours for them to get gross and I don't want them to stand/lay in it while I am gone to work. I was thinking a litter style bedding where the poo will not be right at the surface and need to be changed every couple of days. Or, is there a sand or something similar to kitty litter that would be safe?
