Hey Wheelz, if you plan to split and grill those yard birds, maybe your guests would like Teriyaki chicken. I've used this a bunch for chicken wings, leg quarters and breasts. I don't know why it wouldn't work for split fryers.
Chicken Teriyaki Sauce & Marinade
1/4 cup brown sugar -- packed
1/4 cup soy sauce
3 tablespoons lemon juice
3 tablespoons orange juice
2 tablespoons salad oil
1/2 teaspoon garlic powder
1 tablespoon orange peel -- grated
Mix first seven ingredients and place along with the chicken parts in a Zip-Lock bag. Marinade 3-24 hours, turning frequently. The longer the better. Boil the marinade after the chicken has been marinated. Broil or grill chicken until done, basting frequently with the boiled marinade
