feed quantity

yesterday morning at 8:00 a.m. jason and i filled the bowl 2/3 full and threw two extra cupfulls on the ground. i threw in a couple handfulls of green weeds. in the evening when i let them back in the coop, there was a thin layer of feed on the bottom of the bowl, so i think that is about the right quantity (though as I think we have discovered, there is no "too much" for chickens).
