questions on feather sexing...

[BlackWatchLady]

can a chick that is BA/EE be feather sexed? Just curious..

reason I asked is I brought a couple in for pics, and the shorter wing feathered one reacted to my finger wagging like this...

while the longer wing feathered one was like this...

Tadkerson's post covers feather sexing fairly well.

I doubt you can feather sex it. I have not looked at the breeds in Tadkerson's post lately, but an EE is a mix, not pure. Since it is not pure, you don't know what the genetics are. That is why I doubt you can feather sex it.
