To quote MPC "Hey, chicken addicts! Did you outgrow that eenie-weenie coop you started with last year?"
Ahem. Yes, MPC I did outgrow the chicken coop I started with THIS year. You see, when I purchased (from you) my coop built to house "12 - 15 chickens" I was naive enough to believe you. Being new to chickens I assumed I was making the best purchase possible for my girls - even though it was a stretch financially. So now I have a 6 x 4 foot coop with a dozen hens living in it. Not exactly the 4 square feet of space per bird deemed adequate and healthy. This "custom" Amish coop was also built with inadequate ventilation, and way too many nest boxes (6) for the half dozen birds it SHOULD accomodate. I did build a more than adequate run, with plenty of space for them, so thus far they've been fine - they're outside almost all day and only go in to sleep. However, with cold weather in the not so distant future I am now scrambling for ideas to increase their living area before it gets cold and becomes an issue. For anyone perusing the forum, having not yet started with chickens, be aware that most companies and many individuals who sell coops vastly overstate the number of birds who can be housed in them. As someone on BYC schooled me earlier this year, "You might be able to stuff a dozen birds in there, that doesn't mean they'll be healthy or happy about it". Amen. Hope someone learns from my mistake. Search the coop section of the forum and read all you can BEFORE you begin, you'll save yourself time, money and aggravation in the long run.
There. Feels better having gotten that off my chest!
Oh, and to Adopted Chickenman, I agree with the other posters, when weather permits, close them in their new homes for a few days. Once they're comfortable roosting some place they seem to tend to stick with it.
