In reply to lnlogauge :
Predators are a concern, especially with recent fox sitings on top of the snakes, possum, raccoon, hawks, bobcat, and bear(never here but spotted within 2 miles regularly).
My first step is spending considerably more and using hardware cloth instead of chicken wire for the chicken tractor. Since I'm getting 4 inch wire mesh for tomato trellis, I'll probably use that too, at least as a floor, but possibly as wall reinforcement. The coop will go inside, up off the ground with a ramp that can be pulled up from the outside. I'll probably drop a rod vertically through the hardware cloth, as well as use a padlock or keyring. There will also be a tarp over most of the top, to provide shade and keep the birds at bay.
If the predators do get really bad, well, I can review some Elmer Fudd videos. The brief period I had ducks before, I drove 4 pieces of rebar into the ground, wrapped it with green plastic fencing, and didn't lose any until they dug their way out, so there's hope metal will suffice.
The plan is to let them roam around the yard most every day, and just put them in the tractor at night. With our rain though, I'm not sure how possible that will be, which had me worry about keeping them entertained, but I've been hearing that hanging a head of lettuce well keep them occupied.
When it comes time for winter, if we like having chickens, I'm going to park everything on top of a sheet of plywood beside, or possibly inside, the carport, then throw down 6 inches of straw and wood chips, and put some boards around the sides to cut the wind. Put a small heater in the coop, and maybe drop down an incandescent bulb on a timer. It would be much better for them if I actually get my billboard doors up this year.
The every other Sunday chicken swaps start the week of Saint Patrick's day, so I'm hoping when we're ready in April some older ones are available.
