Combine the maple syrup, orange juice, wine and rosemary in a small saucepan.
Over medium heat, bring it to a simmer, and let it cook gently for a few minutes.
Meanwhile, cut hens in half, down the center of the breasts, along the breastbone, and along the spine. Pat them dry with a paper towel.
Gently pull the skin up from breast, creating a pocket.
Spread 1/6 of the orange zest in that pocket, over the meat.
Place the hen half in a baking dish, skin up.
Repeat with all 5 remaining halves.
Salt and pepper the tops of the hens.
Brush 1/3 of the glaze over the hens.
Bake at 375 degrees for about 45 minutes, or until a meat thermometer placed in the thickest part of the meat reads 180 degrees (or until juices run clear.)
Half way through the baking, brush another coating of glaze on, and again when hens are almost done.
