3 week old Gosling, swollen leg

[Henryshatchlings]

One of our goslings has a swollen knee and is not weight bearing or walking. She is eating and drinking and doesn’t seem to be in pain when the leg is touched but it it’s very swollen and obviously causing her to be unable to swim, stand and walk. Any ideas what we can do to help her? Photo of said leg, any help GREATLY appreciated. Thanks in advance

How is your gosling doing?
Could you post a few more pictures of the joint from a few more different angles?
Are you able to bend the joint, or does it appear to be fused together?
Did this occur suddenly, or gradually over the course of a few days?
What are they being fed?
