Swollen hock joint on Faverolle?

[RuffIedFeathers]

I noticed this joint on one of my faverolles feels larger than the others chicks. Both sides are similar. She is about 7 weeks old. I'm not sure if this is her norm, or if this is swelling/abnormal. I'm not too familiar with this breed. She is acting normal otherwise. What could cause this? Any advice on what I should do?
Thanks!

Does it feel hard or soft? Is it movable? It doesn't look normal to me, but not really sure what it is. Could be a cyst, tumor, bone deformity, infection etc. If it's movable then more likely a cyst. If it's hard then more likely bone or tumor. A vet might be able to advise and offer treatment, but it also may not be something you can do anything about. If it's not getting bigger and not bothering her, then I would just watch.
