If you’ve got a smaller yard or garden then perhaps plans for chicken coops isn’t what you should be looking for – you should probably be concentrating on something designed specifically for the purpose: plans for chicken tractors.
Now if you don’t know what a chicken tractor is (and I’ll admit I hadn’t come across the phrase until a few months ago) it is nothing to do with some kind of motorized buggy for hens! In fact it’s a smaller chicken coop with wheels and quite often a set of handles.
