What are your thoughts about quitters—eggs that start to develop but quit along the way. Is it more likely due to the incubation process or some genetic flaw in my hens? I’ve had a higher than usual number of quitters recently and I’m wondering what’s going on. I’ve used a variety of incubators. I have 5 separate Brinsea ‘bators, and it seems to happen regardless of the ‘bator. I also raise a lot of Araucana, so I suspect I may be breeding tufted to tufted and getting the lethal gene. That would explain a decent number of the quitters, since they tend to be blue eggs.
