If you used a cuckoo (barred) hen with an RIR or NHR roo you would have sex link chicks. The boys would have a white spot on their heads. I'm not sure if it works the other way around
I will, I would love to get everyone's opinion. I've got to get DH to do it. He put this fancy operating system on our computer, I'm lucky I can turn the thing on!
My Cuckoo Maran x Jersey Giant peeps are a month old now and I really have no idea what they will "be". I figure rooster but time will tell. First pic is about 2 days old. The dark chick we lost and the two left are the ones that have the light areas on the top of the head. Second pic was today a they ventured across the yard. Barred coloring is coming in, I am surpised at the yellow legs and feet. Both parents are not yellow at all.
