I took all my broody's babies away, cause the Sizzles r sold, & gave her 3 BO chicks. I hadn't had them in the brooder yet, but let them dry 24 hrs, or so, in the hatcher. She seems to be doing ok now, but about 20 min after I gave them to her, she left them in the nest & went wondering around the run. So I shooed her back in & blocked them all in there. They finally crawled back under her. Of there is food and water in there and plenty of room to potty, but how long should I keep her blocked to be sure they learn her "language"??
