This is only the second time I've let a broody raise a couple of chicks. The first time I was letting the hen and chicks mingle with the flock (I had a creep set up for them to get away to). All was going well for a couple of weeks, then I found a scalped chick hiding in one of the nest boxes. I'm letting the chicks I have now mingle with the flock while I'm in there cleaning. Tonight the mama went to roost and the babies jumped right up there with them. I was afraid that when the others went to roost they might get too rough with the babies so I tucked them safely in their crate inside the coop. Am I being overprotective, perhaps a bit paranoid, because of the first experience? Chicks are 4 weeks old btw. Thanks!
