Limping, swollen leg with hard bump

[Cparkermarie]

Hey my polish hen (1y/o). Has been limping for a while and we noticed her leg at the joint was swollen. We’ve been trying to keep her comfortable to heal but recently we noticed a growth/bump on the same leg but not by the joint. She doesn’t have this bump on her other leg.

Any ideas what it is?

That bump is just her spur. Nothing to worry about.
