What kind of bird should I get?

We are moving into a house that has a bird coop in the back yard we don't want it to go to waist because its really nice but we don't know what to put in it Ive heard chickens are to much work Guinea Hens are too noisy and ducks require water but there isn't room for little pool what else is there and don't say you dnt know because that's worthless to me thank you!!
