Hello all. I have been incubating and hatching my own chicks for a few months now. I've noticed that my RIR chicks (the ones that come from both my RIR roo and a RIR hen) have different colored legs. Like some of them have yellow legs, and some have gray legs, like some EE's. Is it from the roo's bloodline, maybe? He was a rescue, so I'm not sure where he came from. My adult red hens I bought from a feed store as babies. I'm not worried, as they are all healthy....just curious. Thanks!
