I am working on my third batch of new chicks, since I began my life as a Flock Mistress. The first year I brooded week-olds, and taught them everything, myself. The second year, I brooded 8 more, and kept them separated from the group until they were about 10 weeks old. The first batch had a harder time coming to grips with new concepts like where to lay eggs and is it safe to go outside. It occurs to me, as I am about to have a hatch (8 days), the second batch had such an easier time of learning everything, because they had other hens to show them where to go and what to do. I am leaving the broody and her eggs in the general population, because she is fierce, and because it makes more sense to have them grow up as part of the flock, and learn how to do everything from other chickens, than to try to get everyone to acclimate after the fact. Seems my older birds do a much better job teaching young chickens to be good chickens than I ever did. Just an observation from my coop to yours. Brightest Blessings!
