See, here in my township, we have several zones.. I am lucky, I am ag, but the guy right acrossed the street, he is zoned residential... I was very careful about checking the I was with in the right zone for my chickens. The only thing I can not have here is a cow or a pig. I can have a sheep or goat or even rabbits with my chickens... Their should be a zoning map with in your country, find your property, and see what exactly your property is zoned as, what zone code it has I mean, and then read what is allowed or not for your zone and be armed with that, or prepared to get "permited" to have your girls.
I don't eat sell my eggs either. But they do on occassion fall out of my fridge and get cracked, so I have to dispose of them in a fry pan, or meat loaf...
