yes, thats the problem i'm having. Is that every shed seems to cost at least $1000 and that is way out of my budget. So far i'm just doing with what i have. i also have all of my chickens separated for breeding purposes and i'm thinking that a few smaller coops would be better than one large one.
I had the same problem during my search. I scoured craigslist and other buy/sell/trade sites for sheds and found the least expensive/most roomy structure that was portable but built to withstand the elements was an ice fishing shanty. I bought a 4' x 8' one built on skids so it can move when I want or need it to for $250. I installed 2 old windows sashes that open awning style using scrap lumber to frame them out and covered the openings from the inside with hardware cloth so they have plenty of ventilation.
