I had heard that chickens love BOSS so I bought a bunch for my flock of 4 silkies. They wont even look at them let alone try them. A few days a ago my husband and I noticed them eating wild blueberries off of the bushes in our back yard. They absolutely love them!!!! We went blueberry picking today and brought home 12 pounds of blueberries. Would it be ok to give them treats????
