Out of our recent hatch, we have two chicks that are (now) known to be the results of our Light Brahma roo mating with our RIR hen. I was reading up last night on sex-linked traits, and was wondering if anyone was knowledgeable on the RIR trait for rapid-feathering? Both chicks resemble the Light Brahma more than the RIR - white with black markings, and feathers on the feet. One chick is very noticeably more advanced in its feathering... longer, fuller wings, and prominent tail and lots of foot-feathers, where the other has shorter wings and hardly any tail at all... just a poof, and just a little bit of feathering on the feet. It's really quite cute! But it got me thinking... does that mean that I got one of each sex? And is rapid-feathering a RIR trait? I'd be curious to know. I don't have any side-by-side photos, but I can take some if someone wants to see. The chicks are less than 24 hours apart in age. Thanks a bunch!
