It's illegal for me to sell ducks in the city where i live.
I would eventually let them breed just so i don't have to make the long trip to pick up more and I would like to see if they can raise the babies by themselves, from hatching, etc.
I read on here that the babies should not be allowed into the regular pond, since they can drown, and if they have access to water it should be very shallow, like an inch or so and that they shouldn't be allowed to get too cold.
My climate would be pretty decent (80s) around their breeding/hatching time, so that would be in my favour without having to use a brooder/incubation setup and let them try to raise them naturally, which i would prefer.
Of course, it would be a good excuse to have some baby hottentots in my own house!
My aviary is pretty small, so i think most people on here said 2 pairs would be the ideal max capacity, maybe 3, but i think that would be pushing it.
