! Great to have you here. Sometimes craigslist is good...checking around on farm and ranch store bulletin boards you'll see something. I hope you find the perfect coop for you and your birds!!
I keep watch on Craigslist for Free or cheap used sheds, coops or even a dog house for your size! I also have emailed the local shed companies and ask that they call when they replace an old shed and bring it back, typically very cheap!! Good Luck and the possiblities are endless!!! But mind you~ YOU WILL NEVER STOP with just chickens!! LOL
