I have some 4 weeks old chicks I'll get pics of tomorrow. Plus I have eggs to set.Looking good! Lots of color variation, but that’s to be expected. I see a few with a down color reminiscent of what I tend to see. I’ll be mighty curious to see how they all feather out.
Hopefully you’ll see darker heads in the chicks, without the ridiculously annoying breast spangling that birds like mine have. Your f1s had amazingly clear breasts.
