I have a 3 pound feeder. Been filling it up about every 3 or 4 days. I have 5 chickens. When the feeder is filled in the morning. By nightfall the next day. Walk in to the coop and the feeder is spilled with all the extra feed on the ground. The feeder is usually un the ground. With the feed. I have the feeder setting on a good size cement block. I haven't suspended the feeder because the way the heat lamps are at the top of the coop. The coop is an old milk barn. I have been thinking of what I could use. To put on the top of the feeder. So it wouldn't get knocked over. Any Ideas?. Once all the feed is on the ground. I wait about 2 days before filling it again. Chickens scratch the ground. So I figure they can eat the feed off the floor. I have a cement floor with pine chips on top of it...When I cleaned the coop out this time. Their was a large amount of food in the shavings.. To me that's a large waste of feed. So do I feed them outside in the run and take the feeder in at night.? Do I get like a 4 cup measuring cup and feed that amount. I figure that should be enough for a day. Feed that to them in the run during warm weather and feed that to them inside the coop I'm winter. These are 2 year old laying hens.Don''t free range them because of my Basset hound a nd a hawk who frequents our place. Don't want to provide dinner for either animal. I would love ideas. Thank you for your time.
