It sounds like a decent plan. At six months they will have reached a really slow growing phase and several should be laying. Eat the ones that are not laying, makes selection of which to eat easier.
They will not be anything like store bought. The carcass will be much smaller and the ratio if white to dark meat will be darker. They will be too old to fry or grill, but should be perfect for my herb-baked recipe. I posted a long version a few day ago but basically cut the bird into serving pieces, coat them in herbs of your choice (I use basil and oregano), and bake covered at 250 degrees F for about 3-1/2 hours. Make sure the lid is tight so the moisture does not escape. Even Aart would like that one. There are plenty of other good recipes for older birds out there.
