I hatched 10 chicks on March 26th, 4 are black with some white and 6 are mostly white with few having a black spot or 2 on them. My question is are they sexlinked? When i bought the parents i was told my rooster was a dominique and the hens are Isa Brown, It's my first time hatching and I've read that dominiques are sex linked and so are isa browns? But not sure if the same applies if the 2 breeds have offspring together?
