The only thing that's really stopped me recently is the ordinances where I live. And I live on main St with lots of neighbors so it's not like I can "hide" much of anything.
I'm really researching the ordinance change. It seems that since my yard is fenced, that I may be ok. There's one person on city council with a stick up her butt that seems to be against back yard chickens, but the others seem ok. From the minutes I've read they keep overruling her anyways

she's one of those "it drives down property value, it's an eyesore, blah blah blah" types. One member even pointed out that many of the communities in our area have opened up to chickens and just have semi-strict ordinances in places (no roosters, not allowed to run free all over the place, etc).
Hubs is totally on board. He's the one who initially wanted chickens and I kinda scoffed at it at first but with the way we go through eggs, having our own hens would be nice. Plus, fresh eggs just taste better. And chickens are the only birds that don't totally freak me out lol
So I think the plan is to get all our stuff in line to do it next year. We have to re-fence the back (rickety old picket fence). We already have the fencing, it was left by the old owners, just have to get it put in. The garage basically acts as a privacy fence from the one neighbor (the one I think would have an issue with chickens, grouchy old man). Both the other people I can find that were approved don't even have fenced yards.
My biggest concern is the dogs. Funny enough, I think Kaizer I could train to be ok with them. But the lab? No way. He has wayyyyy too much prey drive.
