If you are a large scale farmer or simply has a lot of birds to feed, a high capacity automatic chicken feeder is recommended. But if your flock is small, say around 1-50 birds and you do filling of the feeder every couple of days, a simple hanging poultry feeder will suffice. The good thing about chicken hanging feeders is that it can still be set on a flat surface to allow feed. These hanging feeders range in price because of of the size and weight. The size depends on how much your chickens eat and how often you will fill it with food. Often for these smaller flocks, you can select a size that you only have to fill once every day or every other day. If you do choose to hang the feeder it will create less of a mess. If you are feeding once per day a feeder of 10 pounds or less will do.
If you are dealing with more than a hundred birds all hungry and cackling for feed. You will need a feeder of approximately 20 pounds or more. High capacity feeders that hold 110 lbs and can handle 400 chickens per day. These feeders can be a bit expensive, but well worth the cost. The simplicity of pouring a bag or two of feed into the unit and forgetting it is priceless.
Feeders are also available with automatic opening and closing lids that are perfect for keeping other birds away like crows. The chicken walks up, the lid opens, the chicken eats and walks away, the lid closes. Saving you from putting in additional methods to keep away other birds from eating out the chicken feed and even infecting the feed.
