I have three duck eggs that will be hatching soon, one already is internally pecking but hasn't pipped yet. I heard that placing them in cartons to hatch helps a bit, and wanted to know when to place them and how. Any help?
I don't use cartons, but if your eggs are already internally pipping, they should be in the hatcher with increased humidity and getting into position for hatch. Personally, I just lay them down on the wire floor and they hatch fine.
