Hmm. I was thinking you'd end up with a staggered hatch. Which is a serious problem if you have a broody setting on the eggs, because she'll abandon the ones that haven't hatched yet. ... but when you're doing the incubating, your problems are a little different. Your chicks are going to be different ages. And even if they're just a few days different, the little ones can end up being crushed by the bigger ones if they're all in the same brooder. I've lost purchased chicks that way, if one was a little smaller. They all huddle together and the little one .... just can't shove his way out.Yeah now that I think about it, it would interrupt incubation.
