All the books I read said to make sure you cover the wood shavings with papertowels the first few days because the chicks won't know the difference between their food and their droppings. I have to admit that I thought "yeah right", but it's TRUE!!
I do know one thing.... I'll be glad when this phase is over! It looks good for about 30 seconds and then someone does their business and it's all over except the cleaning up!
