I have learned what t his cheicken math is and told my DH and he cracked up and then said it is true. We started out that we were going to get 8, but then just rounded it to 10, but after trying to find what all of us wanted and to arrive in a time frame where we could have enough time to get things ready we ended up with 26. So he said "yup I can see the chicken math".
6? now wait you need to learn chicken math, you start out with 6 but you may end up with 20 or more, so you better think some on size. ask BHep if you don't believe me.
