Adding Incubated Chicks to Broody

Last Monday my broody hatched two of her five eggs. Of the remaining eggs, one was infertile, one had gotten cracked and the other was still alive but she had abandoned it so I put it into the incubator and it ended up dying anyway. On Thursday, my eggs in the incubator started hatching. Of the ten eggs, seven made it to hatch. Five hatched successfully and two died during hatch. On Friday night, I put my five incubator babies with mama broody. I wasn't sure she would take them, especially since there was a four day difference in the babies, so I only put one with her at first. As soon as that baby chick started cheeping she started singing and cooing to it and fluffing up her feathers inviting him (or her) to her. She accepted all five of my "bator babies" and is quite thrilled with her brood of seven (and very protective). I guess it depends on the hen, but to anyone else wanting to put their bator babies with a broody, I would encourage it.
