My chicks are about 5 days old now. They are extremely curious and love anything new that I put in their environment. First I put one of the straw mats from their shipping box on top of the paper towels. They all climbed on it and immediately went to sleep. They continue to sleep there and haven't really pooped on it. They love to peck at it and pull on any loose stands. I then took a second straw pad and mounded it up and put it in the corner. They take turns running up and down and playing king of the mountain. I shredded some colored paper and dropped a handful in. They love to crawl around in it and play chase with a piece. I washed and dropped a few tiny twigs in which they love to drag around but they can't pick up them up yet. What other toys have peopled used?
