If I didn't do anything to screw it up: I think my four eggs will hatch on 7/6 (21 days, right?). One of my Black Stars has sat on them consistantly except for a few hours the day after I moved her nest to a more secluded area. But, following another post, I will have to agree that you almost don't need a Broody or incubator. I could set my eggs on the lawn and it would be hot enough!!!
