Okay I have three Dark Cornish Bantam Chicks One rooster and two females. Can they mate or are they too heavy like Ive seen said in some websites? Now also I have one Black Australorp ( hen) chick will he try to mate with her??? Cause if he's going to try then I suppose I need to keep him seperate from the hens, cause right now I just want eggs and maybe in two years I'll let him breed if they do??? Plus I have six more hens on the way, different breeds three more Black Australorps and three Bantam Silkies all hens..
