Grow all of your own chicken feed and save money while providing your chickens with a wide variety of fresh foods that are more normal for them to eat than dried and processed grains. Whether you raise chicken just for the eggs or if you raise them also for meat, buying chicken feed can add up.
If you are raising meat chickens you may end up breaking even on the cost of raising your own over buying from the store. They will taste better and probably be raised more humanely but buying the feed raises the cost. In this article from Make It Missoula you will see that you can plant all sorts of things for your chicken to eat and once established you could in the right climate never have to buy chicken food again.
You will see a whole list of perennials and some annuals that will work as chicken food. The best part is the chickens can simply eat the different items so you won’t even have to worry about feeding them. You may want to use portable runs to move them from one section to another as things ripen at different times.
One thing listed to grow for them is mulberry trees. This is because the mulberry will drop fruit for much of the summer and the chickens will eat the dropped fruit which provides them with food that even contains some protein.
