There can be some variation of coloring in the black copper babies. Some have more black than others. Its not unusual to have some off white coloring on the chests and faces and wingtips on bcm babies. I had one that was almost all black on her face when she was a baby. If the breeder has black copper and blue copper Marans you could get either Black copper or Blue copper babies or even splash babies if two of her blues mated. Some of the darker blues can look black especially when they are younger. If you post your pics I am sure someone can help you out.
Ok thanks. She said her blues and blacks were seperated for about a week before I purchased eggs from her. So I'm not sure what I'll end up with. Truth be told doesnt really matter at this point. I'm happy with any of them. My last attempt to hatch shipped Maran eggs did not turn out so well. I got 0 out of 12 last time. I had bator issues though. I did get 10 out 15 this time. Thanks for the info and I will post some pics later. Oh one other thing. Is their a way to sex BCM chicks at this age? Other than the vent checking thingy......
