I agree with you SeeNSpots.. I think the one does it because of his owner... he only does it the morning after she has been out. I really think the other just does it to piss us off. If I keep his bucket at half full during the day...(just incase he goes in it) he never does it. I fill it at night before I leave... next morning, he went in it.

Oscar - They are usually stabled from 4pm-8:30am. They get turned out everyday from 8:30am to 4pm, weather permitting.
