Plan on taking time, as in months, at least!
Here we have about 1/2 acre fenced for the dogs, out the back door of the house. Serious fencing, after one of our adult rescues ignored the Invisible fence if chickens were available. He was the eighth dog we had on the IF system, and our first failure. We added 4' horse fencing, with electric tape above, and the IF about 3' inside the physical fence. Worked great, until a couple of years ago, when the 'mother board' failed, and a newer rescue dog dug under and killed MANY chickens! The IF was redone, and all is well since.
Our birds usually can range anywhere except inside the back yard fencing, although there are occasional losses to other predators.
This spring everyone is inside because of the avian influenza.
My chickens went right through two strands of hot wire last summer to get into the vegetable garden...
Electrified poultry netting works well, although we don't have a place to set it up effectively here. That might work to keep your birds and dogs apart.
