I consider that an excellent idea. We all have our own tastes and preferences, find out how you like it.I will try frying a few to see how their meat and skin texture are at that age.
No they don't. You can certainly cook them that way but you have more options. The way I cook 5 to 6 month old cockerels or 8 to 10 month old pullets after aging is to cut into serving pieces, rinse off but do not dry. Put those pieces in a baking dish with a tight cover. Cover it with herbs, think herb crusted. I typically use basil and oregano and sometimes add parsley. I grow and dehydrate those so I have and use plenty. Toss in a rough chopped onion, a clove or two of garlic, a carrot and celery, and bake at 250 F for 2-1/2 to 3 hours. Carefully remove with a slotted spoon, the meat can fall off of the bone. The liquid makes great broth.I know at 5 months old their meat and skin are like rubber and needs to be stewed or used to make soup.
If you cook one this way let me know if you still think they are like rubber.
