Hen has swollen painful feet

[BarredRhodeGold]

At any rate, if your hen appears to be suffering, or unable to get around, I would think about putting her down. Then it would be good to contact your state vet or poultry lab for a necropsy. They will be able to identify either the gout or the MS, or whatever she has. You may want to try giving her aspirin to help the pain and inflammation. Dosage is one 81 mg baby aspirin twice a day, or you can crush one 325mg adult aspirin (or four 81 mg baby aspirin) in a quart or liter of water. Here is a good link that you may want to save to contact your state vet or lab:

She's still able to move around quite a bit, as she walks from her coop to all the way to the other side of the yard every day (which is quite far). She definitely has some discomfort though I'll try the aspirin for now. Thanks so much for your help!
