I use Little Giant for my buttons, and I get great hatch rates. When they go on lockdown, I but a damp piece of burlap on the floor of the incubator to keep them from getting their legs stuck in the mesh. I use paper towels for the chicks. Paper towels come in all different flavors. I make sure I get a brand that is textured and a little rough. When they first hatch, I put the feed directly on the toweling and I use a peanut butter lid with marbles in it for water to keep them from drowning.
