Hello everyone. This is my 1st post. I have a small flock of chickens that are in 3 separate pens. I have a pair of black cuckoo english orpingtons in one pen, a chocolate English orpington rooster alone in one pen, and a black australorp rooster, a RIR hen, buff orp hen, BLRW hen, chocolate english orpington hen, and 3 black australorp hens in another pen. First let me say I did not put them like that, I've been taking care of my daddy and came back home to them like this. I decided to hatch some chicks since I've not done so in about a year. I started small, had temp issues, got back into the swing of things, ended up with 2 babies hatching out. One is blue, which I assume is from the BLRW hen, and one that my husband and I jokingly say came from the grocery store. This is what I need help understanding...this chick is a buff color with dark brown stripes down it's back and has feathered feet?! Did the stork deliver my baby? None of my birds have feathered feet and I've never hatched a chick this color(s) before either!? How did it happen and who did it come from? I thought all the chicks, besides the black cuckoo pair, would be black except the blrw chicks could turn out blue laced or solid black. Please correct me and explain how this happened. Thanks a bunch. And I'm very elementary on my color genetics comprehension level too, thought I would throw that in.
