This is very weird: I came home and the chick feed jar was empty and a ton of food was on the floor of the brooder. Today, I see what's going on: one of the chicks is just pecking at the food and scooping it down onto the floor. It's as if there is something in there she is digging for. It's a little aggressive, AND it's wasting a ton of food! What is this?? I tried yelling "Ruby, stop that!," but shockingly, that doesn't work .
