Depending on your goals and if any of them are laying, I would feed a grower or all flock (or a layer if they're actively laying) maybe 18-20% protein, to help them get back on track with a nutritious diet. Provide oyster shell on the side for calcium if any birds are laying.
Haven't dealt with leg mites before but others advised above.
If you're worried about mites I'd get someone to help grab one or two of the hens and check their vents, under belly, under wing for mite activity. If you don't see active mites (or lice) then I wouldn't treat them for anything. If you do see active bugs/eggs, then permethrin would be your best bet.
