I've seen several references to chicken feed for litter, but my search really didn't give me info except some people are going to try it. Could someone with experience describe it and compare it to a commercial litter? I use the inexpensive sophisticat for my three young males, and my geriatric 17 year old female gets world best, because she has a touch of asthma. Would love to have a clay free, minimal dust litter for minimal price. Is this it?
