My grandma made these gingerbread houses years ago and they were just given to me, so I brought them to school. The kids loved them! One boy looked in the chimney and said, "Well! There are no Chimney Swifts in this chimney!" That was pretty funny! In case you didn't know, Chimney Swifts are a unique bird that sleep in chimneys, but otherwise they fly all day long without stopping. They eat, drink and bathe while flying! That is such and interesting bird behavior!
