This one looks just like my babies when they hatched. Lordy, I love my Cochins. Mine came from Blue/Blue breeding also. The darkest one is black with gray underneath, I've never see the color before. But he was a tad lighter than the one in this picture so I'll bet the one in this picture is going to be a real pretty black. They're so precious.
I put the tiny OEGB in with my Silkie girls today, she's been inside because everyone beats the feathers off of her (none of the OEGB get along lol!) But the Silkie girls took her right in, I knew they would. She's snuggled up with them in their building right now. I'm having rotten luck getting these OEGBs to co-exist. I got the 2 groups at different times and it's looking like I'm going to have to have 2 separate living areas for them.
