CHICKENS ARE:
-easy to care for and can teach kids responsibility
-totally entertaining to watch & better for kid's minds than tv/games
-provide fresh & healthy eggs that are not raised in cruel factories
-make free organic fertilizer & recycle kitchen food scraps
-naturally control bugs without the use of earth-polluting pesticides
-make less noise than most dogs/parrots,.....
Pets that "give back" - what a novel concept! Change ordinances that are too strict or apply to get a special variance. Best of luck with your efforts!!
