The hen is a Barred Rock. She has been like this for about 2 days, and has been through two epsom salt bath treatments. She has been favoring the other foot, only setting down the injured one when completely nessesary. If anyone knows what is causing this and how to treat it, I would be forever grateful. This is a friend's hen and she is very beloved. (Nature always seems to select hardships on our favorite chickens, doesn't she?) Thank you guys in advance!
