Winter watering for ducks and geese; being away
We converted an 2 bay shed into a poultry house, One side has ducks and geese, the other side has chickens. They both have exterior runs. We don't currently have any water out there--everything has to be lugged from the house. During the warm weather the ducks and geese have had several containers including kiddie pools. Because they (runners) dig in the dirt they have made a large mud pond in their run and the water is almost immediately dirtied.
I'm wondering a few things about winter (here in zone 6)--what size/shape/material waterer is best (I have 9 runner ducks and 3 geese), how to keep the drinking water from being fouled and what kind of heater to use specifically,
Do waterfowl NEED to have swimming pools in winter or just drinking water?
I may need to be away for a few days at a time and can't find a poultry sitter--how to best handle water needs?
