Find a Purina dealer is your other choice. OR buy what you want and mix your own .A few flyers have feed shipped in from Canada.
Why may I ask you are not interested in them? I flew on their feed -the number 2-for 20 plus years.And Yes they have changed in the last few years.
There are a number of feed stores in the Dallas area that handles Purina pigeon feed, I am sorta wondering whats wrong with Southwest myself, there is a lot of fliers here in Fort Worth that use the number 2 as Don mentioned, I am using the pellets for my breeders and will be using the number 2 as soon as the guys get together and place a order to save a few bucks. I think they order 75 or so bags at a time. They will custom blend too.
