I'm sorry to hear about your poor babies injuries. Here's what I usually do when I have an injured bird.... First and foremost, I separate it from the group. That alone can work wonders as the other ducks don't really "care" that their feathered friend is injured or not feeling well. Most of the time, unless it's really really mild, which in this case it doesn't sound like it is, I not only separate it, but I bring the injured bird inside the house so I can keep a close eye on it. I have several large dog crates that work wonderfully in times like these. That way you can keep up with and know for sure how much food and water your little duck is getting. So now that you've provided a soft warm bed, away from grumpy duck friends...give a little extra boost with some VetRx or another vitamin supplement to help be sure it's getting a little boost to the immune system. Give the little guy some fruits and veggies if he'll eat them too. In almost every case, any time I've had an injured bird, they are usually back to their old selves in about a week or so. I had one little duck that was attacked by a wandering dog and I thought for sure she wouldn't make it. She couldn't walk and she had a hole in her side where he literally bit into her. I brought her in, cleaned and treated the wound, kept her dry and quiet, gave her vitamins and plenty of fresh food and water, and within about a week and a half, she was ready to go out with the other ducks. Not too long ago, I had a chicken that got behind a cage I had outside. She had gotten back there to lay an egg but when trying to get out, she somehow wedged herself in and was stuck in a horribly awkward position. I didn't realize she was back there till the following morning so by this time, she had literally lost all feeling in her right foot. I thought FOR SURE she was going to have to be put down and for a little over a week, I got even more sure because there seemed to be no improvement. It was about two weeks into keeping her inside and giving her antibiotics that she suddenly just stood up and decided she was going to walk again! I would take her out daily for fresh air and sunshine and she got a lot of TLC but thank God I waited and didn't put her down! To see her now, you'd never know that she was in such bad shape that she couldn't walk. She still has a bit of a limp, but she's ALIVE and she's happy! I'm no expert by any means, but I would bet that your little duck will be just fine after a few days of rest, relaxation, and some good ol' fashioned TLC! Hope this helps!
