Mine don't have a clue what to do with BOSS. But then again, I didn't toss any into the coop litter for them to discover in the scratching around process. Hmmmm. I just tossed some into the covered run because I'd not picked up any mealworms nor hard-boiled and chopped any eggs for them or given them any shredded cheese lately.
They looked at the black seeds in the run, sideways, then up REAL close, but then backed off like the things might jump up and get 'em. Maybe the BOSS will be gone tomorrow.... I hope so. I have this huge bag I bought, thinking, whoo hooo! BYCers say they'll love this stuff!
Then again, my chickens thought cooked oatmeal was something horrible in their treat dish, and the small cut up pumpkin was some sort of chicken killin' alien thing.
I didn't like rice or spinach or Chinese food when I was a kid; maybe my chickens will "grow into" liking BOSS and pumpkin and oatmeal when they get older.
