That's a great idea! For this hatch I won't have to worry about marking the eggs, simply because I am getting blue and olive eggs and I do not have any blue or olive layers. Next time, I will. I like the idea of the separation after the hatch. Thank you!I'm sure someone also answered this, but here's what I do and it works well to prevent reintegration issues later. I just let the hen stay on the nest- just make sure you MARK THE EGGS and pull non marked eggs daily, because other hens will get in there and lay eggs. And I mark my calender. Then, on hatch day, I have a wire front I can fit on the nest box and I put that on to keep other hens OUT and to keep the chicks from falling out. After 24 hours/all eggs hatched I move mother and baby to a seperated area inside the coop, where they're away from the others but can still see each other. This area has it's own small run, but within a week I start letting them in with the rest of the flock, but I watch closely to see how well the mother protects them from other hens (btw, if she does a poor job I wouldn't let her raise chicks again...). So far the two hens I've let hatch chicks have done a great job protecting their chicks from the other chickens. I did keep the chicks separate for a while after the mother stopped caring for them (they typically stop around 3-4 weeks) because the others were picking on them... I kept them in that same separate pen just until they got big enough to defend themselves.
