Some other breeds you could consider are white giants or sex links (RIR over BR or NHR over Delaware). Everything I've read said that white rocks grow slow but I had a pair from 3 days old until 10weeks and both topped 36oz. in that time. The sexlink suggetion is base on reading, everything I've seen says they are a good mediocre bird in both egg and meat production, the former is easier to come by and marketed more strongly. Personally I would invest in the parent breeds and breed my own but those crosses are available from most hatcheries.
