Title pretty much says it. I have a two month old Cornish cockerel, a two month old Light Brahma cockerel, and a straight run Japanese Bantam chick (with an awfully big comb for it's age). I currently have nine two month old pullets, and three adult hens. Assuming I'll separate or rehome the banty if he is a roo, are two heavy-ish breed roosters too many for 12-13 hens? All hens except one (a Lakenvelder) are heavy breeds.
