Texas has a law that you're allowed to have up to 6 hens and 2 beehives in your backyard. Hens are fine because they're not roosters (though usually one hen will take on some of the role of a rooster). I'm not sure about the wisdom of keeping beehives in a suburban backyard though because when your neighbor mows their lawn nearby they can get irritated and attack -- the hives really need to be 20ft or more away from the fence.
