Thank you.
One chicken does seems a lot for one person, but cooking smaller portions tends to use as much energy as cooking a large one. The oven (or grill) doesn't care if its one chicken, two chickens or just a leg/thigh combo, it is going to use the same amount of energy regardless.
Thank you for the comment and the compliments :)
I agree completely ma'am. It's the same energy one uses to cook the chicken no matter the size. It's better to conserve energy.
You are welcome Ma.
