Pat,
I raise Anatolian Shepherds - this is what they are made for, so I'm not worried about that part. Ideally, the birds will be locked in the coop at night so the dog will just need to keep an eye out for things trying to break into the coop. The run will be covered, because I do want guineas as well, and I've seen them in trees.
Bryan,
I will be mixing chickens and guineas
probably mixed flock breeds. I know a few to avoid.
Not spending much
Weather - we are in Ohio, so all four seasons
Predators load will depend on where we land, but as I mentioned, I raise Anatolians, and they will do a pretty good job deterring predators.
laws wont apply, we will be far enough out that it will be agricultural areas.
Skill - you mean building skills?
I want them for bug control and a few eggs.
