Make sure your area and state allow for you to have them and have permits and regulations for keeping them. As far as taming them, don't expect them to be like a common domestic duck. They take LOTS of time to even have them get comfortable around you or even eat from your hand. Always make sure everything is secure, have everything planned out, and get more advice from multiple bigger breeders and caretakers that own them to give you extra personal advice. They normally hate being held, so never force hold them or they'll be absolutely afraid of you till they die, and that might even kill them. They're very easily scared and if in the wrong environment and stressed, that will most definitely shorten their lifespan. If you want them to be really comfortable around you, make sure your environment is suitable for them to survive and thrive. Don't scare them or make sudden/big movements, sit down with them ( they may cower in the corner ) Hold out your hand slowly and carefully with their feed for a couple of weeks it'll take them to get used to you and start eating from your hand. They most likely won't stay on your shoulder like a parrot, so don't try to force them to. They do good with others of their kind, so other Mandarins or their only relative, the Wood duck. ( or both ) They need a raised nesting box to sleep and lay eggs in, even if you're not planning to hatch and or sell eggs or juveniles. They can do better in winter, but still need side barriers to keep them from seeing outside and flying away ( clipped wings still allow them to fly, but not over the tree line for long periods of time unlike if they weren't clipped or
pinioned) They need a netting on top so if they get scared and try to fly away, they bounce back and safely land down without hitting a hard surface and breaking or killing themselves. They can eat regular mazuri waterfowl duck feed and need lots of vegitation and extra bugs and worms to eat and snack on. Always keep them in pairs, if you want to breed them, never breed the sibings with each other. Keep them on the ground and not on a raised platfrom like a hutch. Theyneed clean and flowing water where they can swim in and clean themselves. River pebbles are the best to have since they need a clean area to live and trive in, so you can easily spray the pebbles and they'll be clean. There's still much more to learn, so always do extra research on multiple websites and ask more professionals about Mandarin ducks
I had previously replied to another person asking about ringes teals, so I'll copy and paste my rely just to give you an idea on other things to think about......
"Look at your area and your state regulations on if you can own this breed of duck and if you have the space/time/money/permits and regulations. Look at where you want to purchase your birds. Mallard Lane Farms is personally my favorite and cheaper than most places besides personal/small ( or hobby ) breeders. Think about if you want their wings pinioned, clipped, or fully winged. pinioned is where they surgically remove the flight feathers to make them permanently flightless. ( P.S, they may still be able to flutter in the air for only a couple of feet. Exotic ducks are much different than Mallards, Calls, and other common and domestic ducks. ) Where would you want them to be? On open water or in an enclosed aviary? They can't really be on open water during the day and in an aviary at night. Do you want them as breeders/pets or just trying to populate your area with teals? If you want them on open water, the best is to get them pinioned. However, pinioned birds are usually stressed more when they feel like they can't fly away, and being pinioned isn't comfortable for them. If you want to keep them in an aviary, think about how many you want or may want. The best is to go bigger. 1 pair can survive in a 10x10 enclosure but always do best in bigger and thrive in bigger areas. Keep them on the ground, don't put them in hutches. This kind of bird needs lots of fresh, clean water, an extremely predator-proof enclosure, warm areas ( they're not good in colder areas ), and much more. Nesting boxes can be raised or on the ground, but for a better chance of them breeding and being happy, getting something more like a wood duck box will suit them better. They need a clean area so adding predator-proof items underneath and river pebbles on top can be easily sprayed down and cleaned. They need lots of vegetation to hide in and eat. For a top, the best is to have a cage like a dog pen and have netting under the dog pen top so if they get scared, they don't choke themselves or kill themselves by hitting a hard surface but a net that bounces them back. They can eat regular duck feed from mazuri fowl feed for ducks, but they need more like extra bugs and maybe veggies. They tend to like to stay with their own kind and not any other duck breed, especially domestic ones. They stay in pairs so make sure to keep them in pairs and not breed siblings with each other. There's much more to learn, so make sure to do more research on your area and the duck itself."
