Yes, the Blue Copper male looks good at this point, looks as though you will have some blue also, these are out of the eggs from Julie right. My best suggestion is give them all the time you can before doing any culling.
Kevin and myself are getting ready to cull some young males here this week and send them to processor saturday , Out of the first 150 we might be able to keep maybe 5-6 males and will keep a couple with extra brown on the breast.
