I would go with ducks, they will be dropping eggs long after a chicken stops and when chickens don't With right coop for them, they will drop eggs in almost all temperatures. When it starts dropping below 0°F is when they start slowing down and around -30°F they stop all together. Duck poop is safe to go straight on plants too and they only need a body of water if you want to breed them.
