It is interesting to me that they have even shown up in your birds, Kathy. This must be a recessive trait from very early on in Delaware history, since you are starting from scratch it must have something to do with the genetics of combining the two parent breeds. I am just starting to learn all this breeding stuff, and the little details fascinate me.I cull green legs.
I sure wish everyone had culled the substandard birds through the years. Yours are the first I have seen that are even close to type.
