Trough – A trough feeder can come in many sizes and be fixed to the side of a coop wall or be an independent/standalone container and even have its roof. Troughs allow several birds in a row to feed and because they are open refilling is easy. The slimline build and high sides make it difficult for birds to scratch feed out by feet or beak; especially, when the trough is fixed to a wall. Unless the trough feeder is a large stand-alone unit with its roof, it should be positioned out of the elements, and if it is too small it will get knocked over so it should be fixed to something. Being an open feeder it can be used for all types of feed.
Open container bin – Open container bins are similar to a trough but not as long and therefore can become crowded with several birds trying to eat at the same time. Utilizing more than one container placed in different areas can help negate overcrowding. Open feed bins are easy to refill and are great to use as a supplementary feeder along with other feeders or as a special treat container for scraps, wet feed for worming medication, etc.
Basic feed dispenser – The common commercial feed dispensers come in all sizes from very small to about 20 kgs (40 lbs) and are usually made of UV-resistant plastic. They can be a cost-effective feeder; although, some prices are ridiculous depending on where the product is purchased so shop around. Galvanised dispensers are even more expensive to buy but they do last longer and are a more durable product lasting for decades (potentially). This feeder holds up to 15 kgs (30 lbs) of chicken feed. With its high sides, lip, and segment bars it keeps feed loss to a minimum. The side deepness can also be adjusted to suit the top screw. Dispenser feeders work well by releasing feed as it is eaten from the enclosed container. The feeder can usually be hung to keep out rodents, and prevent birds from scratching dirt or pooping into the feed, plus, it helps deter chickens from roosting on the feeder. Placing the feeder on a thick concrete tile or brick can also help keep the feed free from debris
