Hahahahahahaha!!!!
I thought your thread title was "question about CHILDREN" and when I started reading the post, I was thinking "why is she talking about chicken when she wants to ask a question about children?"
My snafus crack me up sometimes.
I agree with Arctic Mama. Sometimes you have to settle for "close enough" and kinda flesh out the rest. Altho I know a lot of people who prefer to weigh & measure, I go for the general consensus of what two or three websites post as caloric value of a food. If it says 100 calories, I may eat a little more or a little less & can't be positive it's 100 calories on the dot. So I'm going to say 125 calories. If it's less, then yay! If it's more, I'm probably not off by that much more, so I won't freak over it.
