chicken tractor

"Hens on Holidays", that's what we call our chicken coop these days having converted one old caravan into a mobile chicken tractor. We completed the first one a few months ago and the chickens have loved it (as has the paddock!), so thanks to our current Helpx's (Basile, Sophie & Adele) we started another caravan reno today so we can house more chooks this way.

Why did we embark on the chicken caravan, mobile coop tractor project?
