I went out to check on my broody welsummer whose eggs are due to hatch tomorrow. This is her first time broody. She started out with 15, and I haven't checked under her since about day 8. There are 8 eggs left tonight. Looks like she's been breaking them. There was one broken in the nest that had rotted, and one other was open and empty. There was a dead chick, fully developed, with part of its head eaten. I don't know if it hatched on its own and she killed it, or if she broke the egg and then worked on the chick.
Should I move her eggs under one of my other broodies who I know is reliable, or would it be a problem to move them this late? I've had a broody minorca who killed every chick that hatched under her, and I don't want that to happen this time.
