Last night I slipped 3 (1 week old) chicks under a hen that's been broody for at least a couple weeks. I went out to check on them this morning and found 2 of them outside the box and 1 happily adopted by another hen that has 2 (3 week old) chicks. I slipped the 2 back under the broody, but she isn't talking to them or really showing any interest for that matter. I'm wondering how long to wait before I take them back? Obviously they need to eat and drink.
