I have a regular styrofoam incubator with the wire in the bottom over the water trays. Now that my first few chicks have hatched, I'm a bit concerned that wire may be rough on their little feet. The edges of it are pretty sharp, also. Has anyone ever had any problems with this? I am an overprotective mom, so leave it to me to worry about this! I thought of putting paper towels under them, but they are so active right now they would probably just run right off of them.
