I live in a small rural sort of village, in town and it seems like half the urban blocks have a mini pony, a donkey, goats, chickens, sheep or alpacas in their backyard lol.
Dads got chickens, I'd check with the council but I love having them here. Fresh eggs everyday and Buster is surprisingly good with them.
I love watching them contentedly poking around the yard, they're gorgeous.
One thing to remember though is that they will rip up the garden, we have to go around every couple of days and rake all the top soil and stuff into the gardens again. Most of the plants here are pretty mature so they don't actually do much damage, just mess it up but atm they're 100% confines to their run because we've just put in the vegies for next year and don't want to loose all our seedlings.
I know a lot of people that have they're chickens extremly tame, I house sat for someone that had 3 as pets for their kids and you could just walk over and pick any of them up and carry it around.
