I usually brood in my breakfast nook. I talk to them all the time, look in on them a lot, and at least once a day, I catch each one, hold it, comfort it, then transfer it into a clean brooder box with it's hatch mates. I try to hold them at least once more during each day, and comfort them. Like I said, they go through stages as they grow. They get used to the routine of being talked to, handled, and transferred to a clean box. At a certain age, suddenly they act like they've never been around a person. The get all skittery again. A few days later, they settle down. Especially for treats. They do fine for a bit, then all of a sudden, they're scared again, then they get over it again. Usually by the time I put them in the coop, and they adjust to coop life, they settle right on down, and are fine after that.
