Well my JMF XLD birds are now 7 weeks. I weighed all the males (63), average was 225g, ranged from 198-261g. Kept 13 that weighed 240-261g with average of 248g. All the others are already in the freezer. Next week hope to go through all the hens, weigh and cull. Don't know how many I will keep for breeders until weighed. Getting a lot of eggs for 7 week olds, gathered at least 3 dozen from the two large grow out pens tonight, some really huge too.
