My incubator is an old Hovabator, still-air model. The floor of the incubator is a metal grid that is warped and doesn't lay completely flat. I have tried straightening it out, but just can't get it to lay flat. So when I take the eggs out of the turner on lock down day and lay them on the floor, they roll around like crazy. I am afraid the rolling will damage the baby chicks, so I have been using popsicle sticks on 2 sides of the eggs to keep them in place. Does this present a problem for the chicks when they try to hatch out of the egg? Or should I just let them roll around?
