Don't write on CDs and DVDs with a ballpoint pen. It will destroy them. You can use a sharpie.

Hello to you!

The oldest book about the chicken tractor that I can find is Chicken tractor: the gardener's guide to happy hens and healthy soil by Andrew W. Lee published in 1994 by Good Earth Publications, Shelburne, VT.

Is he the inventor or were there chicken tractors before that?

Thank you,
Ambie
