Twisted ankle: Ok, this happens quite often to ducks and geese of the like. The subject will walk around with an ungainly limp. Don't worry, it'll heal in a week. Sometimes the symptoms reoccur, but the wobble will most likely heal by itself. No need for splints/bandages. Ducklings are also susceptible to splayed leg, which means its habitat is too slippery and it should probably be changed to be more study.

Bloody nose: WELL, this only happened once. It was quite freaky..and of course, it was my oddball Goose, Zach. He was just walking around with blood streaming out of his nose. As in humans, this means he's dried out. To cure, I just fed him a lot of lettuce and bread soaked in water (along with just water), then separated him from the other geese for 2 days. He recovered nicely.

Poked(Gouged out) eye: OK, this isn't too common.. BUT IF IT DOES HAPPEN.. it's best to remove the subject from imminent danger(that's obvious ^.~), pet it and feed it until the eye gets better. Duck eyes can actually regenerate quite well. There's no need for human medicines, but if you're really worried you could take it to the vet.

Angel wing: This is a common occurence. Geese/ducks that are fed food that is rich in high-protein and growth supplements will find their appendages growing in crooked. NORMALLY, it only affects the wing, where it will grow conspicuously outward a few inches. Oddly, my chinese gooses' tail grew crooked instead. To fix this problem, either change the type of food or just exact less to the subjects. Some say that a sling will help to correct the deviant wing, although it is extremely difficult to get the sling to stay on without the bird being hurt. A better method is to exercise the subject's wing by pulling it out straight and moving it up and down. Then, place a rubber band on the wing to bind it together. It may take a long time, but the method is 100% effective.

Dry, cracked feet/legs: Alright, this only pertains to ducks. It occurs when the subject does not have enough water to wade in. Thus, the feet become awfully dry and it starts to peel. To keep the feet lookin' fresh, supply a bin in which the duck can wade . This may not be too important health-wise, though it is more aesthetically pleasing. However, i've read somewhere that some ducks do require a lot of wading water.

Choking: Okay, so this used to be an abnormal occurence. It never happened to my mallards..but the pekins and other domestic ducks are very apt of choking. My geese never had the problem, but then geese are built to swollow a lot more. Pearl actually choked on lettuce, TWICE. Another one of my ducks' neck swelled up about 1 and a half inches in diameter because he ate too fast. If it's really serious, the duckling can die. Should this happen to you, it's best to leave the duckling in place. Give him water mixed with vinegar and make sure he drinks it. If he doesn't, force it down his throat with an eyedropper (or whatever it takes). This method is also highly effective.
