All my birds are hit and miss on Copper. Some have very nice copper and some not very much Copper. I have at least 3 Blue Copper pullets looking pretty good. I will try and get pictures.If you have nice blue coppers that is a different situation. I have worked on blue coppers and just can't make any headway with them. I am throwing in the towel. If your blue coppers are good quality hang onto them. I need the pen space for Black coppers so it was something I've been thinking about doing all summer. I only raised blue copper cockerels this year, no pullets and I only have 2 hens left and plan on parting with them soon. All of my cull black and blue copper cockerels are being dispatched this evening. There are 8 total so far. One marbled eyed cockerel was a reprieve. His copper is nice so I'm going to let him hang out and watch him a little longer.
