Thanks. I have a question about single vs double barring. I understand that the cockerel is single barred. His barring appears to be confined to his tail, saddle, and hackle feathers. When he was a chick, he didn't develop obvious barring until around 8 weeks. Another cockerel in the same hatch, a blue Barred Rock (blue Orp x Barred Rock hen) feathered out the same way. I thought I had another blue Orp until the barring appeared at around 8 weeks (apparently, my Orp hen was sitting on a BR egg, she didn't actually lay it like I thought <g>). Until them, I thought barred chicks would develop barred feathers when they first started to feather out. Is the fact that they carry only a single barred gene the reason the barring didn't appear until later?I bred Black Copper Marans for 5-6 years the really black chicks were always a clear sign that we had a recessive color pattern [e+, eb, or eWh]. Your Orpington is build on the extended black [E] primary color pattern and cross with a legbar will have the Extended Black [E] with a recessive Wild type [e+] and should have a really black chick down color. Your cross was a success. Everything came out as it should have. Congratulations. The Oliver Eggs are great additions to the flock.
