Hi, I came home from work today and noticed there was cardboard at the bottom of the temporary brooder. It's a huge appliance cardboard box, covered with lots and lots of clean shavings. I also noticed that my chicks food was still quite full. Not an ordinary occurance, mostly it's been gone or almost gone whenever I do check. Any ideas on what I should do - feed grit? They are acting fine and still pecking at their food, I'm just surprised their food wasn't almost gone. Although I did fill it extra today since I knew I wouldn't be home to check.
