Hello TammieAnne. Welcome to BYC.
They look too young to tell to me. I can sex some of the chicks that hatch here at 4 weeks but even then I'm guessing. It's not until they start to grow proper feathers that I start to get it right.
Yeah i agree with Moonshiner. Not the best line.....
Females shouldn't have an all dark head like that. She should be lighter tan, with a dark stripe. I'm not going to try and guess, just because they don't show the correct coloring, so i wouldn't know for sure. Post pics of their combs at 6 weeks.
Ya, 11:00 O'clock is iff. It doesn't look like a Legbar to me. It looks like it may have a eb (partridge) color pattern rather than the e+ (wild type) of the Legbar. Do you have any photos that aren't top view?
