thanks! I have had Sumatra's for 5 years. I got the originals 5 years ago, some adults, some young . And for the years following i have been selectively breeding them. I have to assume they originally came from hatchery stock, but the hatchery characteristics have been bred out of them. FYI these were 2 very small roo's. Normally I let them grow a little more before butchering. After we eat these I may change my mind on that.....I'm impressed by the good breast muscling!! NOt what I would expect in a sumatra--now I am rethinking everything I know. Perhaps compared to hatchey stock everything else is likely to be better muscled.
