My Black mottled Orp has mottled legs, but the first gen cross (I named them LegOs, LOL) have white legs. Some of the second gen seem to have yellow.
Yes, I bred the F1 hens with a roo from the same cross. To double up on certain genes before breeding back to their Orp grandfather. The F1's lay...
I notice your Orpington roo has dark legs? Orps are supposed to have white legs. It's no big deal since you're mixing anyway, but I wonder where he got them from?
If you can, waiting a few weeks would clear the leghorn roo from potential fatherhood.
I'm on the second generation of English Orp x...
