the majority of chicken feed sold in the US isn't small bags over the counter - but that doesn't do the original poster any good.Like I said "few" . You are showing feeds that may be popular but compared to the total amount of chicken feeds sold in the USA they make up a small percentage of the tons sold each year.
Nutrena is popular, uses both wheat middlings and red dog wheat.
Purina, too. Or used to. Now their labels "Processed Grain By-products" as somewhat less enlightening. Wheat Middlins in the Flock Raiser, likely in the other products as well..
Believe it or not, I'm trying to help the OP out, not argue semantics over total poultry feed sold in the US re: wheat content to non backyard flock owners.
