We have 2 white Silkies (one rooster /one hen), 2 Silver Spangled Hamburg hens, and 2 Golden Sebright hens plus a newly hatched chick that was a surprise. The Silkie hen was broody - laying in three eggs that we never figured would hatch. Today she emerged from the coop for the first time in several weeks. When my daughter picker her up...Surprise!...there was a dark colored chick peeping away on the ground. We created an area in the coop separated from the other chickens by wire fence to protect the chick. The mother hen appears to be very attentive, so we are leaving the chick with her. Any advice is appreciated.
