One of my hens just had four babies. One of them is clearly a barred rock. But it would be a barred rock farm mutt mix. (Mom is true barred rock, dad not so much.... ) I have three barred rock hens. None of them have given any sign of becoming broody at any point. But, I was thinking about moving the new barred rock who I suspect is a roo, into the small coop with the three hens (when he gets old enough obviously) and not collecting eggs just to see if I could get some barred rock chicks. Since the chick is not pure bred, I would do it just because I like the black chicks. Bad idea since he's not pure? Bad idea since he would be potentially mating with his mother?? Thoughts?!!
