I have 24 in all On grower still and I go through about 50 lb bag every 3 weeks or so what I did Is I put in on cup of feed per chick I put 2 cups of feed in the big feeder per Teen chicken that seems to make it last and if they run out they will have to wait for the next feeding but they do have scratch and table scraps they eat as well I just do that with the feed.
