They have the greek yogurt in bulk @ the BJ's near me. its like 4 bucks for a big container. i maybe give it to them once or twice a week if im feeling generous!!!
Now don't take this the wrong way but there is no such thing as "holy crap". Your not to far from Syracuse for me not to come down there. Then again what ever your chickens got I don't need it. I hope they get over it before you say worse things.
