That is so true Marcy, I had a few of those also a while back. The only thing I noticed with the red stars is that they aren't as big if you want to butcher any and they didn't seem to lay quite as long as the blacks. The blacks that I had were a much meatier bird and seemed to lay a year or so longer then the reds. I still have one black that is probably 5 or 6 years and still see her in the nest once in a while but the egg is smaller now. About the same as my RIR's that are in the layer flock.That is so true, and the Red Stars lay really well, too. They both seem to burn out pretty fast, though, after 2 years egg production drops drastically. I've hatched my own sexlinks, black and red, but they didn't have the selective breeding MM puts into their "star" hybrids, I don't think they laid like them.
Love my RIR's but can't beat the hatchery stuff if you are selling eggs to help pay feed bills. lol
