Huh, I didn't know about the bars coming thru. do you mean dirty, like the dirty gene? Where it dulls its feet? Because I didn't know that affected the color of a bird. Here's one of my dirty birds....View attachment 1872652
No that's different... I think. I'm just going by blogs and posts on pigeon genetics, we'll see what if anything I really get. I read that ash red spread/lavender spread/mealy spread (all the same mutation apparently) is variable and affected by a lot of modifier genes. The clearest spreads come from checks or other patterns, while birds that have the genes for bars tend to show faint bars through the spread. That seems to be the case in the German Owl x Lucerne Gold Collar cross I posted. That cross also isn't pied, so if Rosie doesn't carry hidden pied factors I can surmise their chicks won't have much white.
I'd be happy if it turned out that they have lots of hidden genes and I'm wrong and their hypothetical chicks come out totally unique and surprising though.
