What does 'wing patch' mean?
Here's an Isabella rooster expressing the wing patch issue.

Yes. Its retarded feather growth.
I believe that was my first Isabella rooster. (May of been my second)
I had never seen or heard of it before. Its from the combination of the lavender shredder gene on duckwing.
I remember contacting other breeders about it back then and saw it in just about every Isabella rooster pics. None acknowledged it. Sad, Isabellas may have been more popular by now if more would of worked together back then.
 
Correct females don't express it. Its probably not a popular opinion because most say they carry it sight unseen so its impossible to breed out without test breeding.
It happens because of the shredder/fray gene associated with lavender reacting with the wing patch of duckwing males. Shredder issues do show on females and if you breed that out you're breeding out the wing patch issue.
When I had it I looked at it as one in the same and breed to get rid of it as a whole not separate issues.
It pretty much shows as soon as the males feather in in that area. The feathers just don't develop and stay like pin feathers. It does become more obvious the older they get.

So in a perfect world breed females without shredder genes to males with no wing patch or shredder genes?
