I've hatched a fair amount with broody hens in the past, but am new to the whole incubator world. I've been researching older threads and came across a post by Speckledhen way back in 2007 about late hatching chicks. She stated she's read late hatching is hereditary and culls the eggs at 22 days as this is not trait she wants to continue. I'm wondering if this has borne out for anyone here? I know a lot of you folks do massive hatching and would be interested in your input. Do you let eggs go late as a rule or cull for this? With my broody hens I've never really worried about it. They hatch when they hatch, and when she leaves the nest any that haven't hatched get tossed.....so I guess that's kind of the same thing, isn't it? Maybe I've been culling for this all along and just never really put it into words
