I had one of my Ameraucana/ Easter Egg hens go broody. By the time I realized that she was broody, she had quit laying eggs (in my flock of blue and green egg layers, she was the only one who laid pink eggs.) After researching how to "break up" a broody hen, I decided the least cruel thing was to let her hatch a few. She stayed in the nest box in the henhouse until the eggs hatched, (the other hens were around her at night and when the weather was bad) and I left the chicks with her to join the flock.
My boyfriend was worried that it wouldn't be safe to let the chicks out with the flock, and considered separating them from the momma hen to raise inside. But I think it would have been worse, to try to introduce them to the flock later.
As it was, the other hens soon learned that if they tried to peck a chick, they would have a furious momma hen in their faces.
I'm not sure how long it was after they hatched that she resumed laying eggs. At least a month. But I think it was worth it for those chicks to have a real "mom".
If anyone with a broody hen wants some Easter Egg eggs, I would be willing to send them on short notice, but it takes an average of three days for USPS Priority, and I only want to ship on Monday or Tuesday to avoid getting caught on the weekend. I don't know how long a broody hen would be willing to sit.
