We tried the shavings, but I am pretty sure my girls like hay the best. It's easy to clean because it's lightweight, can be picked up and the droppings fall to the floor to be shoveled out. Also, a little goes a long way as far as fluffiness in the nest boxes. The girls dig around in it and make everything perfect, then start all over the next day after I've cleaned and put some fresh handfuls in there. Also, it smells nice.
