LOL bro... hay means dried grass, of course it's dry! 

besides timothy, i think alfalfa also do find (maybe better, i'm too lazy to check the nutrient contents), just ensure that the stuff given are not sprouts (too high protein).
that is good food also. you can either let them graze or cut the grass for them to eat.



grass = good  , just make sure theres no pesticides/chemicals/etc.
