It's always amazing to read the posts by everyone and how everyone's opinions are soooo very different!
What might be a mistake for one situation is a great deal for another. And after 8 years of owning birds, I'm still learning myself. I love being on the property we are currently on - giving me options in paddocks, pastures, runs and housing.
I love using "used" items and giving them new purpose. I like that I'm not on a main road anymore so that as we collect stuff to use at a later time it doesn't appear to be as "trashy" as it might (does) look to an outsider. And over Christmas I diminished the piles of pallets I'd been saving that my husband was complaining about and now have 2 new 4x8' coops that are at each end of an 8' x 64'ish run w/ a large tree in the middle (run not complete yet); 3 new 8x8' coops (2 not completely done & occupied yet - I had the stomach flu last weekend, over the clearest/warmest days of course, and when better i literally cried as it rained/poured/froze for the other 2 days I was off work

) & another in the works. None of the 8x8's are totally done - no pop doors that will allow chix in/out when going to pasture/run yet, but getting there - for now they go out thru the people doors). None of them are built exactly the same - different sizes of material, different materials used. The pens do set side by side and back to back so that communal walls could be used... mostly open air.
The four pens that were here on the property when we moved in - 3 of them now have hooped roofs - so after ducking under the 3-3/4' door frame, you can stand up. The 4th needs to have the tin & wire removed then it, too, will be hooped and birds will/should be happier. I will definitely be happier!
I've learned about and now utilizing the DLM methods - O so much easier to do when I ended up working full time again this past fall and had a hard time getting ANYTHING clean (I was doing good to have a clean kitchen sink, shower, toilet and laundry, LOLOLOL). And the chickens LOVE the DLM that they can dig through. All the NC sand here on this property is slowly starting to see more insect life - which also truly makes the birds happy. Things are coming full circle!
See if there is anyone around you that will allow you to watch and/or participate in culling or processing chicken - since you think you may be doing that. I currently don't have the equipment to pluck feathers (& that is a PITA 4 me & the stench of scalding does make me ill), so I skin our birds. If you can't stomach it - dual purpose or meat birds may not be the way to go at all. I am fascinated by having different color eggs in my egg cartons! Soooo PRETTY! Make me smile when I turn around with a cup of coffee to contemplate breakfast, lunch or dinner. I need a purple egg layer - haven't found out what lays those yet, LOL.
There are many, many more breeds out there than the handful that are mentioned so far in this thread. I've become enamored w/ some of the rarer, crested breeds - that also do well with free ranging and make good table weights (not as fast as american cornish crosses, but who wants a "frankenchicken" anyway?).
My advice - simply get started. You will slowly learn what truly works for you. The posted articles by Aart are great, the article about rotating & culling the flock is great. There are other good and thorough articles. BYC is the BEST!!
