When chicks reach about a month in age they will require some stimulation. They will be hardy enough to go outside in a covered small area on fine sunny days for a couple of hours. In between these outings, chicks will need some interest. They will be able to flutter onto logs where they can perch and scratch at the ground. Food and shiny things are top interesting things for young chickens. Hanging food items encourages the chick to jump for it. Foods that roll, like berries, peas, child safe mirrors and lightweight balls provide hours of entertainment for adolescent chicks. Pumpkin and squashes are natural wormers.
At night, they will still need warmth and somewhere cozy to sleep. It is a good idea to provide a warm hot water bottle under the sleeping area.
