We buy 40# bags of them wherever they are on sale or cheaper, usually between TSC and Walmart. They are for our birdfeeders. Most chickens free range under those, so I don't feed them any, but once every few weeks, I toss some into the penned ones for a treat.Are all BOSS seeds created equal? and if not, do you have a preferred brand or recommendation? I usually get the Wagner brand in the wild bird feed section. I only have 7 hens.
