Is it possible that it may be too hot for the chicks to develop under mama? I have two broodies, both barred rocks, 17 eggs between the two of them. Should of seen hatching yesterday and today. Aaaaand nothing... I know those eggs are fertile. They have been setting very nicely. I live in ID, and really only the last few days of the 21 day period has been 80's-90's. I will wait it out, maybe I counted wrong. I'm dissapointed because a local gal brought Muscouvie (sp?!) duck eggs to my country store and I thought I may be able to hatch them under my newest broody. Hmmmm Any suggestions?
