Ok 33 days old. Both same parents. Father pure breed Barred rock mother EE (Easter egger). Im thinking the barred one is female she feathered much faster. And has the darker barred coloring of a hen but who knows with the EE mother thrown into the mix. The other in thinking Roo took a lot longer to feather out and just got some tail feathers. Opinions from the experts. I'm usually pretty good but I just was curious what the experts think.
