we have had chickens for about a year. Red ones, white ones, brown ones, mini flewers, and brown and white ones. We have gotten ckickens from different sources. about a week ago we had 10 chicks hatch. we isolated the mom and chicks in fear that they would be killed. we have two roosters one dom. and one with his comb pecked off. is it safe to let the mother and her chicks loose with the rest of the flock?
