He said that that was the natural angle of her feet, and that donkey feet can be a lot taller. The john that came with her had almost no angle to his feet. The farrier fixed that a bit, but for the most part that's how they were supposed to be :) Donkey feet grow a lot slower too,
Can't judge her feet fairly from those angles & hoof pics as per the link in my signature line are needed if you want hoof critique. Oh, forgot but a friend has a good website with a page on donkey hooves, if you would like to look; donkey hoofcare
They shouldn't be taller but can be steeper/broken forward in appearance. If they're tall, as in frog off the ground, that's not correct. They should still conform to the basic principles that apply to horses, & as for horses, hoof balance & what else may be happening in the body will govern angles to a fair degree. *Unhealthy* hooves of donkeys & horses grow a lot slower, but donk hooves don't necessarily grow any different rate at all IMO, it's down to health & supply & demand(You don't use it, you won't grow it). Generally I find the same average trim schedule applies as for a horse - 3-6 weekly is ideal.
Honestly though, I'm thankful for the slight swayback, as long as it doesn't impair her, because it will hold a saddle a bit better.
Unfortunately, while I wouldn't call it swayed, it is a weaker back than straight, so actuall LESS fit to be ridden. If you mean the shape of a saddle, you will need to get one specially fitted, or use a treeless, because it will damage her back to put on a badly fitting horse saddle, particularly onto an already weak back. I'd want to build her up a bit first, before riding much, as well as ensure her feet were in good shape.
