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.

Unless they are all pullets.
