I use 32 oz. yogurt containers to fill my feeders, I also feed 8ducks and 1 goose with 64oz. of FR pellets a day. they all free range but there isn't alot for them to eat right now. I use 50lbs. in a month. And believe me they eat good, also for snack the get mealworm and sometimes romaine lettuce. and some w/w bread but not much of that. plus I use a 7 way scratch grain that I mix into the feed about 5 lbs. to 50 lb of FR. also Boss added at about 5lbs. to 50lbs. you can buy the FR crumbles but my chickens turn it into flour in short order so I don't buy it.
