We live in a res. development on a 75x120 lot. My girls (12) have a 8x10 wood shed and a 10x18 run. the shed is in the run. Our town doesn't care what I have as long as the neighbors don't complain. We have no roos. The town said I could have an elephant if I wanted. We would like to increase our flock with some ducks. I already got 2 kiddie pools. The girls get to roam the whole yard when I'm home. The question is how many is to many? Any thoughts
