I have a lot of foxtail seeds screened from organic soybeans that I would like to feed to 3 week old Cornish rock broilers, I would mix it with there regular feed. Think it would be okay?
If this is what you're talking about https://en.wikipedia.org/wiki/Foxtail_(diaspore)
I'd say don't do it. Any grain with an awn can be troublesome, and that looks particularly unsuitable for feeding.
