I'm going out of town for Thanksgiving. Usually don't need a farm-sitter and shouldn't this time either but with the cold weather our 3 pet ducks have come in off the pond and now spend every night trying to swim in the chickens heated water trough. It's been bone dry every morning and the floor of the coop is a skating rink. I'd prefer to let my chickens and ducks share the big coop-- any ideas how to keep my birds hydrated while I'm out of town? We can put the water outside when we're home but when we're gone we wanted to just lock them all up in the coop for 3 days w/o anyone coming over to chick-sit. Thoughts? Inspiration? Easy fixes I'm just too clueless to think of? Thanks!
