I'm no chicken expert, just a person trying to read up on linoelic fatty acid, but from what I've read high-linoleic acid seeds are mainly a problem when they're refined into oil because it exposes them to oxidization, creating "oxams' - oxidized linoleic acid metabolics.
I think the concern may be large-scale chicken farms adding vegetable oils into their feed for chickens. Do people do that with chickens? I saw this place is putting vegetable oils in their goat formula, for instance. I don't know-- I have no experience in livestock. I saw the same claims about chicken potentially having too much linoleic acid and found this forum trying to learn more.

I don't know for sure but based on what I've read so far, it doesn't seem like unprocessed seeds are anywhere near as harmful as the oils.
