Hay on the floor of a coop gets pooped on constantly, water gets spilled.... Mess happens. Moisture happens. Plus hay gets compacted down with little feet. Without the constant replacing/raking/maintanence the hay will get sogggy, moldy and gross. If you replace the hay and clean...
Sure it is ok. But hay gets soggy, moldy and gross.
But may I suggest you look in to the 'deep litter method'? It uses shavings and you only have to clean the coop out twice a year. Seriously.
