1 what breed of ducks are heat hardy?
No idea, sorry.
2 can ducks be happy in a flock of jest girls?
Yep. So long as you don't get a broody breed, that is (They need a male duck for fertile eggs and babies, after all.) Male ducks are rapists [EDT: Okay, "are" is stretching it. Many drakes are rapists. I've had a few good drakes.]. Sometimes, they'll band together and be gang rapists, especially if they're low on the pecking order, so I don't like to have more than one or two adult drakes at a time. If you do get any drakes, try to keep to a ratio of 1:3 or fewer.
3 what breed of duck lays a lot?
Khaki Campbells and Runners and Golden 300 layer hybrids supposedly all lay a pretty good amount of eggs. If you get a good line of muscovies, they lay a lot of eggs--but they tend to be constantly broody, so that negates this somewhat. I only have Pekins, Swedish, and Muscovies, so I couldn't give a personal account of the first three.
4 do ducks need water to swim in?
No. They only need to be able to cover their heads in water so that they can clean their eyes and nostrils.
5 do i have to get special food for them or can i feed them chicken feed?
You can feed chicken feed, but you have to make sure it has the right nutritional requirements for ducks. You should keep an especial eye on niacin (b3) content. It should be at least 55 ppm.
This is a handy resource from the largest duck hatchery in the country.
6 can call duck live in very very very hot whether? like 105
