Wow 1-2 hens just seems cruel! In Westmont, it's 6 hens & in Downer's Grove it's 4 hens. Even that seems small since our family eats about 2 doz eggs per week. There is of course a loophole if you're in 4H.Western Springs allows 2 hens. They can't be too close to the main house or a neighbors house. Lot lines are not the issue. Unincorporated Winfield Township apparently allows 1 hen. That seem sort of lonely, so I felt obligated to sneak in some friends for her.
