I'm in Lake Placid in Highlands county....this is an agricultural community ) orange groves, cows, caladiums) but some parts are just "residential" and not zoned for "agriculture". I know the city of Sebring allows chickens ( and pot bellied pigs) and I think just 2 hens? im not too sure.Not sure about Avon Park and not sure about where I live, I'm in a little suburb of Lake Placid but live off the main drag/area of my subdivision. I've got 6 girls and so far since they moved out to coop in May I have not had issues from my 2 closest neighbors. My heart sinks and I get that "oh crap I'm caught" cold feeling come over me when I see our busy body "security" drive by lol They stay in my backyard, mainly hanging out by coop when they have playtime, they don't make much noise except before they lay and of course their " I laid an egg" song. I keep it clean and doesnt smell so if someone has an issue, I'll ask em if they want to buy my groceries!
