I currently have 24 eggs in my incubator, and one of my light Sussex pullets has gone very broody. She's been at it a week, so I figured I will move her to the broody pen and see if she keeps it up while I am incubating. If she does, I would like to try and adopt the chicks that hatch to her. I guess what I don't know is, how many can I give her? I don't think all 24 will hatch, but if 20 do, can she cover 20 chicks? If not I can set up a heat lamp in the brooder but I prefer to have them with a mama only if possible.
