I have black australorps and one black star right now. The australorps lay pretty good but not consistant. My black star lays a big egg every day. I just bought 15 RIR pullets at a local farm store that come from estes hatchery the other day. They are getting another order in on the 19th that will have some red stars in it. I am going to buy about 15 of them when they get in. I know they all lay really good, but out of the RIR, black star, and red star, which breed will give me the most eggs, or will there not be enough difference to tell?
