The Post and Courrier has the story. The Monk's website has a statement which in part reads:
It has always been Mepkin Abbey's purpose to provide the healthiest environment for our chickens, to treat them as one of God's precious creatures and to offer to consumers the best possible product for their health and enjoyment. That is precisely why we moved to the cage arrangement over 30 years ago, and why we have continued with it to the present. Cages provide hens protection from predators, soil-borne diseases, and diseases that are caused from walking in litter or waste.
We stand by our product and by the commitment we make to our customers as stated on the inner cover of our egg carton.
