I'm in Walton County, Georgia. We have 5 hens in a moveable tractor, don't regret anything (except the usual "wish bigger coop/more chickens") The back yard sounds familiar: about half acre, just bought the trees for the little orchard, big garden.
- the smell: I've got a routine of moving the coop (well, having the guys move it) every few days. During the drier days, thorough cleaning once a week is fine. Right now in the damp and cold, I spot clean daily as well (removing the poopy bedding, fluff and add a bit more fresh), change water daily, and have the run part covered with a plastic tarp. The tractor is close to the house right now so a drop cord will reach to keep the waterer from freezing. It usually is a bit farther, behind the veggie beds. The only time I smell them is when the weather is just so wet, and the tractor stays too long in the same spot. My future coop will be bigger, have a covered run, and the poop board setup.
- the predators: although we have everything except mountain lions and bears here, the only thing I worry about for real are DOGS. Even though there is a leash law, the neighborhood is full of loose dogs. So I have to keep a close eye out when the hens are free ranging - we don't have a fenced yard (yet). there are a few inquisitive hawks. Our tractor has a locking bar across the pop door and gets locked every night and the food put away.
- mites: are a re-occurring problem for me. I use DE in the coop, dusting the bedding after every clean out. When they get mites (at least I think it was mites, this is my first year) I use a poultry dust a few times according to the package directions.
- poopy butt and the like: no worse than babies. The chicks had been chilled badly when we bought them - the power had been out all night at the feed store. But I nursed a starving 4 week old dumped kitten that was in worse shape. Gently washing chick fluffy butts several times a day for a week wasn't too bad a chore.
- chicken sitting: Got the BIG feeder and waterer from
TSC, so we can be away overnight. Also, both sons are able to come over most times to check on them. It's just the not having the coop's pop door locked up at night I don't like if there's no one to do it. I'm sure our other friends in town would think it cool to play chickensitter if needed.
- cost: most of the building materials were scavenging from packing crates, construction sites. Only bought the 1/2" hardware cloth, hinges and latches. Used leftover paints all mixed together. We are currently saving stuff up for the future coop.
Anyways, this is our setup. Its ok, maybe just a little crowded for 5 big breed birds, but its working so far. And I would just repeat what everyone else said previously. So good luck!
