We had his party at home and I did not want four 9-12yr. old boys running around the house all afternoon, so I sent them on a treasure hunt. They had to solve the riddles on pieces of paper to find out where the next clue was hidden. The boys plus the oldest chick ended up running all over our little town to find the clues. Chicks #3 and 4 had to stay home with us because they do not listen to the older kids so well.
His party was about week after his real birthday so he had asked The Rooster to bring him home a giant cookie from Sam's. I think that it added a few pounds to both the Rooster and I.
