If they're young owls they might have found your watering a fascinating thing. Free entertainment...
Owls are curious birds, so they probably think you're interesting and are trying to figure out what you are (and if they are young, if they can eat you)
They're carnivores so I wouldn't suggest trying to feed them or anything.
it was beautiful and awesome to watch them watch me. They moved closer the longer they were around. just as the first 3 nights with one owl watching me, each one flew off coming towards me and than doing somekind of display with their wings as they flew off, it was amazing... what could this mean..?
