Depends on the male themselves
I would never be able to sell my khaki without his lady as they are a pair
He spends 24/7 by her side
So I get why some only sell pairs
You can add more females to a pair but some boys will only have eyes for the First Lady
I have 16 ducks and mine are all out together yet they stick to their little groups of hatch mates as I have different ages
When my boys get to frisky and start to over mate I separate them from the girls
I keep a close eye on their necks and if it’s looking a bit rough the boys are on time out to let the girls heal up
When I say heal it’s never bad just redness and a little feathers missing in the area they bite to mate
I have never had one with major injuries
My khaki is very good to his lady
When she says no he leaves her be
He never runs her down and treats her like a princess He is happy with just her
But my other boys get a thrill when she runs and so they will run her down to mate. Although she has learned mom has her back and she runs right to me and they get told no and walk away
I have 11 girls and 5 boys
I would like to be less one boy but hard to find them homes as many want to put them in a freezer and I don’t eat my ducks just their eggs
