hi I am a wild life carer and have had a aprox 7 week old duckling come in to care with what appears to be a possible break to a bone in the hip area the duckling is eating and drinking and is now trying to walk on the leg which still has some mobility is there any thing more i can be doing to help out this little duck

Optional Information:
Type of Animal: duck
Gender: unknown
Age: 7 weeks

Already Tried:
this little duck came in to care after it was thought to have benn attacked by another animal. it came in not appearing to have had any breaks in its legs or wings after observing it for the last 35 hours i suspect that there may be a break in one of the bones in the hip area the duck when first presented was quiet and did not want to use its right leg even tho there did not appear to be any breaks grazes injuries to it as time has gone on the duck is now trying to bare some weight on it. when i took the animal to our head carer she reexamined the animal and said there may be a possible break further up as i had susspected as she said there felt to be crunchiness in the hip area upon her exam. I have kept the animal quiet and warm. this morning the animal is starting to put weight on the leg and is trying to walk around. is there any more that i can do?
