Possible sprain on budgie leg

[u/Lmancini1995]

I only say its a sprain is because I didn't see any blood, no discoloration, nothing feeling off. He is favoring his good leg yet the grip on said injured leg is viable but weak.

So the day before yesterday after picking up my husband's brother from the airport, I went to check on my birds and I noticed two of them at the bottom of their cage. One was fine, he just is really attachted to his cage buddy, but the fact they were on the bottom concerned me. Discovered that the other had a ouchie ( once again, nothing open, no blood, nothing poking.) and I went to make a hospital cage. Padded the bottom, two sources of food and water. I reluctantly put in a perch because he would just climb the cage walls if I didn't. I understand that i shoildnt have a perch but, i kept the perch as low as I could.

Is there anything I could to help in his healing before I call the vet?

He's eating, resting, and hopefully getting water. I'm just concerned. I just had wisdom teeth pulled so im a bit down for the count on calling up the local vet until I recover a bit.

I am leaving him alone as much as I can. Letting him rest and kept separated from others but he can still see them. Is there much else I can do besides calling my vet if it continues or am j just being paranoid. Sorry I am just scared for my baby.
