I have been putting my ducks and geese in a pair of these( 6 in each). they are old duraliners that have sand in them about an inch deep. keeps it dry and in the morning I roll them out of the barn into the sun to dry out the poop. when I get home I rake them out and get them ready for bed. the geese were ahead of me tonight and walked in the barn and laid down where I park the bin. I had to shoe them out and get the bin in and then they came back and climbed in before I was done putting their feed and water in. they know that the barn means safety at night.
