Our turkey hen is currently sitting on a clutch of eggs - 7 turkey, 12 guinea fowl, and a duck. She's bee on them for about 2 weeks now. Our Tom sleeps in the same coop at night, usually on the roost keeping an eye on her. 2 Days ago, however, he started sitting in her nest box with her. This morning I went to let them out of the coop and he didn't seem to want to move from the nest. I didn't think much of it until I went back around lunch and found him still not moving. So I took a closer look and noticed he was sitting on eggs. I watched him take a few from the hen and gently put them under him. If he was too slow the hen would take them back but otherwise did not seem to mind. I've read that this apparently happens from time to time, but is it something I should stop? I don't want him breaking them. If I do need to stop it, what' the best way of doing that?
