I'd personally put up a fence too, but (didn't read all posts) bet a golf-course community does not allow such a fence because of it being one big "community" . So, you must re-home them for a while or hide them inside with the diapers. I am sure the "neighborhood police" will re-visit to make sure they are gone. This is why I choose to drive so far to work and live without close neighbors, but that is not an option for most folks. You could make a run in the garage and keep them there, but they are quite dusty with the shavings bedding and such. So, cut a tiny door in the side of your garage, put one of those auto openers on it, and make a stealthy, solid pen out of bird netting and stiff wire, the kind for shade like a greenhouse uses. It comes in 50' rolls. Make the run very short, like 24 inches at most. I'd fill it with wood shavings, as the grass will be gone very soon. You'll have to feed them more fresh veggies and lawn clippings to keep them in greens. Surround it with shrubs, keep it small. Inside the garage, make a small coop with roosts and two nest boxes. Make it solid, with a lift up lid. Surely you can keep 4 little ole hens without too much notice. Just re-home or hide them until all is quiet on the golf front.
I see this scenerio: a dense holly shrub about 4 foot tall running in a rather large square, like a formal garden. On the house-side, a small square dark, box-like space, then evergreen perieniels in front of it, or vines. It could be 24 in tall, 24 or 36 inches wide and as long as your yard is. With enough plant growth, it will blend in. Just some ideas.
Next, wage war on the neighborhood committee to change the rule.
