Ive been experimenting some. So far a Angel Hair noodle will cause a riot in the box! Now all the chicks rush to me when they see me come in. I scooped up a handfull of dirt under the porch to give them some grit too. I also put carrot shavings and banana in there as well. Im not really sure if they ate those or not. I know they pecked at them but nothing like what they do with a noodle.
