Ouch! I'm beginning to think our 40 mile round trip commute isn't such a good thing.
I'd like to have some chickens too, but that might not go over well with the neighborhood for the moment.
A friend of ours has some bantam chickens in town. He gets several eggs a day from them, and his neighbors don't complain. Some towns have ordinances against chickens but most such are against
roosters. You can easily have a few hens without a rooster and they don't make much noise.
It's the cock crowing at all hours of the day and night that most neighbors find intolerable.
There's no way a backyard vegetable garden is going to feed a family all year. It takes a significant chunk of land to grow enough to feed several people for a year. One year we put in about an acre of sweet corn and got a good harvest, but it was only enough to feed us for a year. And some of it we ruined, because we were processing it outside, while burning citronella candles to keep the mosquitos away- and the whole batch that day tasted like citronella.
It's technically edible, but there's still some of that sitting in the freezer two years later. Yuck.
You'd be lucky to get a 1/4 acre garden out of a standard suburban yard. That's enough to get something tasty all summer long, but not enough to put much away for later.
