I was given my first chickens last year. They were 3 and 4 years old. The person I got them from used crushed corn cob for the litter in the hen house. I continued this practice with no problems. It absorbs the droppings quite well. It cleans up easily when I clean the hen house. It composts really well. I notice that no one has mentioned using crushed corn cob on this list since I signed up. Is there any reason for me to change this practice?
