I want to feed my chickens the minimum of a feed I may ferment in order to get more bang for my buck. The will be in a tractor for the night but will be let out during the day, I want them to free range as much as possible to keep my feed costs as low as they possibly can be. I will be doing 25 CX's along with 25 Red Rangers. Also I want them to clean up there feed quick. I am trying to come up with an answer that is as exact as it can get, I would like to give them X amount of feed each day so I can fill a bucket to a line and thats what they get.
