I got these chicks as hatching eggs. They said Black Copper Marans, but these chicks don't look like what I thought Black Coppers were supposed to look like, the Black/white, black/yellow color. Are they still BCM? Also, anyone want to guess as to gender of these and my other chicks? The first three are the two in question. The next a Black Copper Maran, (roo?) Welsummer, then Blue Ameracuana, and last is Black Copper Maran.They are almost three weeks old.
