I am the proud father of my first three chicks. Their parents are IB. The father is split to white and the hen is an unknown split. The three chicks look quite different at two weeks. One is "monotone" light brown, one is a normal looking IB with white flight feathers, and the other is very similar to the second but also has some white on his shoulders. Is it possible for me to have three different colored birds from this pair, none of which are white?
