I have 2 hens that are displaying broody behavior, one is a white Ameraucana and the other is an itty bitty Serama with 3 little chicks that hatched 2 days ago. It so happens that my order of 3 day old chicks came in today. If I gave my serama a few of the chicks, would she "adopt" them? I don't want to leave them in there only for her to later kill them or refuse to sit on them. The ameracana is sitting in the box profusely brooding, even when all the eggs have been taken out for the day. She gets VERY upset when you mess with her, screaming her little lungs off, but she doesn't bite or attack. If she's removed from the box she jumps right back in it 5 minutes later, and if the coop door is closed she'll pace around and constantly check it. She's been doing this for about a week now and I'm wondering if it'd be safe to pop the babies under her? Does she need to go through the whole "21 days ontop of eggs" before she'll take care of them and walk around with them? This is my first time raising chicks the natural way, everytime before has been incubated and indoor brooded so any tips would be greatly appreciated!
