chicken tractor worth it?
I like this design of chicken tractor: http://www.thegardencoop.com/
It's called the garden ark. Things I like are the open top, and the material used on top to let more light in, especially in the winter. If I had my husband build this for me though, I would want the run to be longer, as it seems too short for the 3 chickens we'll have and the coop seems too small on the inside. I'm also concerned that it will be too drafty. I'd want my husband to build the inner area larger and insulated. They say on the site you can lay a piece of plywood over the top of the hardware cloth, leaving a couple inches open for ventilation, but I'm concerned that this would still be too drafty. Any thoughts on this particular design?
Or can anyone recommend a tractor for three chickens that would be well-ventilated but not drafty for a winter that gets down into the single digits at night? We have hawks and cats, but that's about it in the way of predators.
