My chicks are due next Saturday, so I am finishing up preparations. I have read from multiple sources about using puppy pads to line the bottom, so have been considering that. However, there are also pads made to put under human patients in bed. There are "chucks" and other brands. I even found some lined with carbon, which seems like an especially good idea for brooders inside the house. I'm wondering if anyone knows if there is any reason I should not use those? Thanks for any input.
