I used to use a trough style feeder that I made which works fine but when we get heavy winds with rain, it can be a little challenging to keep it dry due to the design of my coop/run. I'm trying out the bucket feeder but I noticed that a lot of feed gets dumped out as they eat. They don't seem to eat any of the feed from the floor so it looks like it's being wasted. Is this common with this style feeder? I might go back to the trough set up and make a set up to protect it from the rain.
