Here's my thoughts...
the smell in hot Georgia summers:
I use laminate stick tiles(cheapy box of them from HomeDepot!) to cover the floor and the roosting area! Clean up is a sinch! not stinky at all I wipe them clean at least every other day! No Biggy!
* dealing with all the ways they die - sickness, predators, accidents, killing each other:
Lost two this year to predators..sad...but part of life...we live in the woods and they free range and we have hawks...need I say more?
* chicken mites:
never been an issue but I think it would be easy to fix
* pasty chicken butts and all things related to poop:
only had one pasty butt when he was a baby ...just wiped him clean once and that was the end of his issues...poop is not a big deal..like I said above
* trying to find someone to care for them when we are out of town, or would we never get to leave town again:
I have a neighbor that keeps an eye on them when we leave on vaca and I tell her she can keep all the eggs!(bonus!) When we're away I leave their chickie door open for my free range egg layer flock so they come in and out of the barn as they please..it's a risk but it's better than someone having to let them in and out twice a day...I guess you could always just keep them locked up for the week if you weren't willing to risk it(that's what I do with my banties) I have a big black rubber buckets (
tractor supply) one for water and one for feed. I fill them up once a week...so they are VERY self sufficient..kinda like having a cat....a little extra food and water and their cool!
* Initial setup cost (mostly the time and money to build a coop that would not be an eyesore):
This depends on what you like but there are alot of nice rabbit huthes that could be easily converted to a nice banty coop! Or a nice cute little dog house with and attached run is cute too!
Our backyard is almost 1/2 acre, but it is pretty full already with a small orchard, a shed, several raised beds for vegetables, compost bins, etc. The space that we would have for a coop and run is around 400 square feet. I started out thinking I would get 4 or 5 chicks, then I got all excited and thought that was enough room for a dozen or so...and now I am starting to wonder if I should just forget the whole thing:
I started out wanted the same 4 chickens!!!(LOL) I ended up ordering 14!!! Now I just hatched out 4 more and have 7 more coming this week!!! Can yo say addicting!!!(LOL) I would say start small! Since space is limited...and they are going to be in a neighborhood..I would highly suggest ONLY buying hens!!! This will help you avoid some problems! If you must(and your nieghbors don't mind crowing??? they can be noisy!!! but if you have to go with one roo(make it a banty for sure!) I would actually recommend all banties to start with ...silkies are GREAT layers and they are super sweet!!! I love my frizzle cochins too!!!(but they aren't great layers!) Or you could do a couple big girls and a couple banties? Start small...this way if you want to add a few new ones next season you can! It's TONS of fun and they are REALLY easy pets to have! I think you'll enjoy it...very easy to keep it you have the right set up and just keep it simple!
