For nearly 9 year's, we have had Rhode Island reds and cockerals and yet, never have they had babies. They have been broody but nothing in there. When we had another variety, one did have a baby but she killed him/her and that is the only time. I have read that Rhode Islands are great for eggs but not for chicks and this seems to be proving true. But we stick to them because of all the varieties we have had, they prove to be not aggresive. Suzanne ps: I should just add that egg laying is not a problem; although not all of they lay. We have 13 now.
