I was unpacking some boxes in the yard yesterday and a piece of styrofoam (about 1.5'x2' and .75" thick) fell out. I left it there for exactly 10 minutes to carry some stuff inside the house, and by the time I got back the chickens have pecked off all the corners and a bunch of holes in it! It's not like they don't have food around, they had plenty of food in their feeder and a bunch of chicken scratch near by. But no, they had to run way across the yard to eat up the styrofoam board! Will they be okay? They seem to be doing fine this morning... Doing things that chickens do best. However, now I'm wayyyy more cautious of what I leave laying around.
