I'm a bit paranoid about bugs, especially with the chicks staying in my house while they're small. I just bought a 50 lb bag of DE. Is this safe to use while they are chicks? If so, how do I use it? I was thinking to just put a little pile in their brooder where they can roll around in it. They loved it when I did this with sand and rolled around for a long time. It seems like this would also absorb the liquid part of their excrement, thereby keeping it cleaner for their little feet. I clean it at least twice a day, but it never seems to be enough! Thanks!
