These are 3 barred rock/north holland babies (Dad was a barred rock, mum was either barred rock or north holland.) Two have yellow legs, one has white (she has the nth holland mum obviously, from the leg colour, the other 2 I'm not sure if they are pure barred rock) They are 8 weeks old, and I'm suspecting roosters because they have some wattle development and their combs aren't little! Aside from that, I find it difficult to look at feather development for clues until it's really obvious, so would appreciate your opinions! Sorry for the terrible photos, why are chickens so difficult to photograph?!
