I was only able to catch one, but the other pullet has legs precisely the same color. Still looks yellow to my eye, but a much lighter color than the cockerel.
Until I can corner all three to check, I'll assume the sole color is the same.
I'll double check, but I believe all the possible BA mothers have white feet. I had two JG eggs but only one hatched so I know for certain that only one of the 4 was a JG cross.
We hatched 4 chicks. Father was definitely Bielefelder, mothers were either Black Australorp (3) or Jersey Giant (1).
All were black at hatch and are now showing considerable barring as teenagers. They also have yellow feet. Three are left, as one was killed in a dog attack. One is a cockerel...
