I saw a thread on here discussing ducks in chicken tractors a bit, but it never really got past speculation into the meat of the subject. What is the viability of raising duck in a chicken tractor (a la Salatin). I have 2 already made from chicken this year and I would like to switch over to ducks. Has anyone seen good sources on people trying this? I'm most interested in the amount of ducks possible in a tractor and the type of waterer to use.
