I'm still confused about "free feeding"? One big feeder for them to eat out of- how much crumbles in it for 21 chickens? As it is we feed two times a day out of about six or seven pans(like pie pans) because the 2 roosters want their own and certain hens run off the ones they don't let eat with them so they run to another pan and it's rather hectic playing which pan can we eat with whom! This goes on about 10 minutes then they scratch what fell on the ground. The couple that don't get enough walk away and I feed a bit to them on the side. They also get treats at lunch of whatever we have left from the kitchen-bread ,veg. etc. This is time consuming so would love to put out something a leave for the day. I want them to free range also, not hang around in the barn yard. Any ideas will be appreciated.
