It certainly seems like raising the chicks makes them happy. I have been busy trying to break my broodies, I have a few too many with broody tendency right now and no need for more chicks yet! In a couple of months I should have fertile eggs again to let them try.
I didn't WANT more babies, but after taking her off the nest daily for over a month I gave in to her demands and bought those two at the feed store. Lol.
