I've had chickens for a few years, but this is the first time I've allowed a hen to sit on a clutch of eggs. Momma hen hatched the only viable egg in the clutch yesterday and I slipped a couple of feed store chicks under her so the one would have company. I made a separate area for the new chicks and mom in the coop, but it doesn't give them access to the outside. How long do I keep the chicks separated from the rest of the flock? Should I keep mom in there with them, or let her out? Now that the chicks are here, I'm really unsure what to do with them.
