I'm not the most experienced at hatching crosses and predicting the outcome, but I thought I had this one nailed. That is, until they hatched. Let me start by saying the grandparents of these new chicks are all hatchery stock, as is the cock/father. The parent stock are RIR x black sex link. I hatched the sex links last year from a cross of black Australorp x Barred Rock. The sex link hens are solid black with some white feathering in the chest, grey legs, etc., as one would expect from that cross. The RIR cock just looks like a production strain RIR. He was sold as a RIR, not a Production Red. The kicker: so far all the chicks hatched from the RIR x bsl are buff! I was sure they should be black. Did I misjudge the genetics, or do I have some impure hatchery stock in the bloodlines? Here's a pic of one of the new day-old chicks. Thanks for any help!
