I've got 6 chicks all under 3 weeks in a long plastic tub. This morning I went in and they had dumped out all the water in their waterer so that half of the pine shavings were wet. I have no idea how they did this since it wasn't tipped over?... (it's a plastic mason jar waterer meant for chicks) Sadly I didn't have time to replace the shavings as I was already late, but I quickly put some fresh water back in there. When I got home 3 hours later, the water trough was literally stuffed to the brim with pine shavings. Can chicks pick up shavings and move them? Why would they want to do this? Do they need more space or something? Are they bored?
