Help !! Slipped tendon on duckling

Help Me !!
I have a month old Mallard duckling. I've just been told by a reputable Vet that treats ducks that he has a slipped tendon. He also told me there is really nothing that he can do. I feed Mazuri Waterfowl starter food and he/she has been well taken care of. I have 4 other Mallards which are the same age and none of the other ducklings have any health issues. They are kept in the house at night in a large pen which has 6 inches of shavings and it's completely cleaned out daily. During the day, weather permitting, I put them in a 12 ft x 12 ft pen which has grass. I let them loose in our acre fenced yard when I am there to watch them. On nice warm days I fill a kiddie pool so they can swim, always supervised. My master plan was to allow them on our 58 acre lake after they where 8-10 weeks old. Sorry I'm so verbose but I just wanted to give you background on how I'm caring for the ducks. This is the first time I have raised ducklings. Two days ago (sat.) one of the ducklings started to limp but still eats, drinks and can swim just fine. I took him to a Vet this AM (Mon) which treats ducks and he diagnosed a slipped Achilles tendon. He told me only 10% get any better on their own and surgery is not an option. Having been a Vet Tech for years I can't sit by and do nothing. I know very little about ducks but would be willing to do what I can. I'm already in love with these ducks they are so cute. Any suggestions will be greatly appreciated !!!! Please help !
Thanks in advance,
Gail

HI there and

First I would like to introduce you to Regie.



Regie is My Indian Runner duck who hatched last November with a slipped tendon. She also has Angelwing- is very small and still even has some of her baby fluff. She is a real sweetheart. She is an inside duck as she has never walked.
I have considered surgery to remove the now wasted lower part of her leg and foot- That way I could make her some kind of Prosthetic- But I think she is still too small and weak to survive surgery. She lives - as you can see from the photo- in a babies portable cot. There is a bit of washing to do every day...But it is just so worth it. I know many of people would consider it cruel... But she is alive and happy- and in no pain. She knows no other life- so She is welcome to make my room smelly for as long as she can. Regie loves to swim and gets very excited to hear the taps in the bathroom running. She goes outside on the grass some days as well.
Ducks that only have use of one leg tend to get problems in the joints of the reamining good leg at times- So its better to keep them in a smaller more confined area to limit them getting around too much. They still need exercise though. Breathing is sometimes a problem as it is hard work hoping around too.

Hope your little one is one of the 10%.

and from Ohio. So sorry about your duck. I am glad you posted this in the duck section. Hopefully you will get help there.
