My friend’s broody chicken just hatched 3 little chicks, they are in front yard same coop with other chickens. First day, 1 died , didn’t see any cut or blood, 2nd day, another one disappeared no blood or feathers. So I took last one away from Mom chicken , put this baby to my 3 weeks old flocks . First time I put hand to her, she bite my hand so hard like her Mom protect her. I made her calm down , give her worm. 2nd day, she was nice to me and followed me around, we are from enemies to friends. Today is 3rd day. She is so sweet. Trying so hard to eat and running to keep up with older chicks. She is happy maybe forget her Poor Mom. But eventually I will return her back to her Mom when she is stronger enough to protect herself.
