HI fellow Buckeye!
I'm Just a few hours north of you, around columbus. If you just drop everything from your schedule and spend the next week reading this forum, you'll find all the answers to your questions, and many you didn't think to ask!!
We also live in a residential neighborhood, though we have about 2/3 acre. Our coop is an old 1935 14'x14' shed that we got for "free", took down and reassembled into a 8'x16' shed, half of it chicken coop. "Free" b/c once we got new roofing, new floor, etc, it was no longer free;-) Don't kid yourself - if you want the coop to look presentable for a neighborhood, unless you are very lucky, a great scrounger and have lots of time and patience (to wait for the right materials to show up) it may cost some $. Best bet is to search craigs list for used sheds, materials, etc. We got some great coated wire for a steal from c.l. My girls (and boys - yikes! no crowing allowed!) get out into the yard when i can supervise, but that is not every day. They do LIVE for that free time, though. We are going to finish fencing the yard this summer (more $), which will allow for more freedom for them. Then i have to figure out how to keep them out of my landscaping beds and garden;-) They are digging holes in the mulch right now. My dog is somewhat afraid of them, so they keep her in line.
We also have a run (8x16) that they have 24/7/365 access to. Our coop is not insulated (and probably a little drafty) and I have had no problems in the winter. (even though my neighbor worries endlessly about them. she is the perfect chicken neighbor - she brings them food scraps daily. but gets very upset when the roosters go bye-bye)
You can also find chickens on c.l. More as spring goes on. Local
Tractor Supply or feed store will have chicks too. They're cute, but won't lay for what will seem like an eternity (20-30 wks). Comets are sexually dimorphic , which will prevent rooster dilemmas! I must say, though that i love my easter eggers - beautiful blue eggs! I got them from a girl who raised a bunch for 4-H (craigs list, again!) I have several different breeds cuz i like variety.
My assessment of the chicken project (after 2 yrs) is this: It is a great hobby. I have always loved animals, had lots of pets and wanted to live on a farm. They require far less care than your average dog, rabbit, parrot, etc. I LOVE eating fresh eggs that were laid in my back yard, but most of my friends think i'm somewhat insane (remember, we live in a residential area - 500K developments less than a mile away.) But it is just a hobby. We don't have the space to make it more than that. Like any hobby, it costs $ and the returns are all personal pleasure;-) We also have two heritage turkeys that are going to become easter dinner. After adding up all i spent on feed, etc, i really think i could have bought a good organic free range bird from a local farm for cheaper - and i wouldn't have to pluck it myself!! But then, I wouldn't have raised my own turkey!
My next project: clicker training my favorite hen to do tricks!!
Sorry- hope i don't sound cynical or even too philosophical, but as I was thinking about how to answer your post, this all just came out. Enjoy your birds, and god bless this forum!!
