I just went on a hunt for poultry feeds that contain zero animal products...I came across this in my search:I will have to read the labels on my feed bags at home, but someone recently mentioned that a lot of feed companies do not include animal products anymore because their feed has a longer shelf life without.

I haven't found any of these said products just yet.
