I got my first 3 Blue Copper chicks hatched out 3/27. I'm breeding 4 hens held back from last year, the best of 7 that I ended up keeping. Got them all in separate pens so I know who's who. I didn't get a decent male last year, so I'm breeding them to a Black Copper. Sure hope I see some improvement in these this year. So many thing to work on! I got set back waiting for the male's comb to clear. I think it was favus, but never knew for sure. Both of my Black Copper males had it. Cleared it up very fast with the formalin/vasoline. 3 treatments was all it took and it hasn't come back. Finally felt like I could put him in with the hens. He's a great guy. I move him every day to a different hen and he breeds them immediately. Not getting any infertile eggs. Don I think you said you move them every 2 or 3 days but I kept loosing track so I just move him every day and it is working out fine. If I can get enough blue chicks from this male before it gets beastly hot here, I'll switch to the other male and hatch some from him, too.
