Thank you to all for respondong.
I now know there are numerous threads on this subject, so I appreciate.
My aim is to make a moveable pen, something not often seen with the dog paddocks. Thats actually the easy part.
Most people use the dog kennel as a chicken run and living area combined.
But I intend to do this differently.
The birds will have a large shrubby "nature area" that I'm enclosing with an electric ribbon. Its really just a scruffy section of the yard, with no real pedigree. It is un-level, has several large boulders and weeds thrive there. There is also a couple of small garden beds I carved out last season. I'm going to add plants that thrive on heat and abuse to the spot:
Pigeon Peas.
Vining beans
More bramble berries
Sweet gum as sedge plants
Annuals: okra, eggplant, late season winter squash
The dog pen will move around the perimeter of this area on skids and just be an extension of that. Its not a tractor, per se, in that I don't move it often. But once it gets enough mulch, clippings, straw, etc, on the floor, I'll slide it over and use the vacated plot as garden space.
Ive done this in the past and it has worked very well.
What I'll have to figure out is how to attach the coop to the side panels, so it can move with the kennel pen. Its my hope someone has done this or can offer construction ideas?
