Do the Hovabators have water channels like the LGs? How do you keep them out of the water? Sponges?since I have one Hovabator specifically used as a hatcher, I took out the wire grate and plastic liner, so I hatch right on the floor of the 'bator with just paper towels layered on it. I don't like using terrycloth since I've had chicks snag toenails in the loops before.
