Welcome to BYC.

Can you post some photos of them both, plus the joints (legs)?

Is there any "oozing" or what looks like infection at the joints (hocks)?
What type of food/treats do you feed?
Any scabs/injury on the bottom of the feet?
Have you had any chickens that had signs/symptoms of respiratory illness (coughing, sneezing, runny nose/eyes, wheezing, lethargy, etc.)?
Have you added any new chickens to your flock recently-if so, were they quarantined for a period of time?

There can be many causes for leg/joint problems. The symptoms you mention makes me think Mycoplasma Synoviae, but there are other illnesses, conditions that can cause this as well.

Separate them both and make sure they are eating and drinking. Offer some poultry vitamins with B2(riboflavin) in them, if you can't find that, crush a human B-Complex vitamin and add it to their feed. Feed extra protein like egg, tuna, mackerel or meat.
