I started considering this project in 2009 and just kept looking at all my options, then in 2012 my Chicken Mobile Stagecoach got under way. I only worked on it in my spare time but one could build it in a week of steady work probably. It's been at capacity with chicks since April of this year but I'm just now getting around to posting pics of the build. You can find the full story at My Chicken Mobile Stagecoach Page here on BYC. Here's a few overview pics. I'll be glad to try to answer any questions you may have.
