I need to setup something for my birds in the coop since their yard is frozen solid. \
The indoor birds are a different matter. I have a recovering chicken and quail in cages. At first I bought large dog bowls for the quail, but they flung sand and stuff everywhere! So I bought chinchilla bathhouses for them. I use dry garden peat moss mixed with traction sand and sometimes I put some of the chinchilla dust in with it. So far, so good. I wanted to use garden soil, but everything I had in the house had pearlite in it, and I didn't want them to eat it. The house chicken gets that mixture in the bottom of a cat carrier, and I put that into the bathtub for easy cleanup.
