I recently acquired 7 ducks. They are Indian Runners (2 males & 1 female) & Khaki Campbells (1 male, 3 females). What is the male to female ratio? There is a lot of fighting amongst the males for the females. I'm afraid the males may drown one of the females as they fight over her in the water. Do they pair off for life like geese do? Is there any special feeding requirements or can I feed them the same as my chickens? I know they need water nearby when they eat so I am providing that. They are free range on 1 acre of pasture along with my chickens & right now there is a ditch flowing through the pasture that will dry up later this year.
