Hi! My name is Crystal, and my hubby and I decided to start homesteading. We started raising chickens (layers) this past summer/fall. One of our hens hatched a chick in mid November! (Didn't see that coming!) Now the chick is about 7 weeks old, getting pretty big, and I'm wondering if/how to introduce him/her to the other chickens, how to tell if it's a hen it not, etc? I'm a little leary because we had two roosters and one got killed, we're guessing by other chickens but not sure why. Help please!!
