I bought a huge bag of BOSS last year.. Christmas present to the chickens? I haven't used much of it at all. Same for cracked corn. I have so much kitchen scrap, I don't find many days where I need a 'treat' for them. It is nice to toss something down to have them busy with for a little while, since their run is a barren wasteland.. these beasties are rough on plants
I planted an apple tree for them and they've about peeled the whole trunk! Hoping the poor thing will survive, now that I put a cage around it.
