hide and seek anyone?

I live in the city and have 6 hens, they live in my front porch with plenty of backyard time. Today was my son's baseball game and it went on until dusk which is not normal. When we arrived home the 6 hens were no where to be seen, I was worried something/somebody took them. We searched and searched, so worried. Here chick,chick, nothing. Then one gave a tweet, they were sleeping under my brussle sprout plants! My yard is a jungle with green everywhere all 6 could hide together even my white one!What a night!
