A few months back, on the Sun. radio show, someone was expounding on the benefits of zeolite being added to chicken food. Does anyone remember the conversation and has anyone have any knowledge of this product and what, if anything, does it do for an already good condition flock.? I do add DE to the feed as well as dust roosts and nests, but if adding zeolite would enhance their appearance and production, I would like to know. Thanks in advance...

Zeolite is a form of clay. Are the chickens getting any form of grit?
