How To Feed Acorns To Chickens

Feeding acorns to the chickens is relatively easy as they tend to eat anything that’s given to them. Before feeding acorns to the chickens, make sure to leach them first to remove all the tannins.

If not, the toxin can make the chickens very ill and even cause death if they consume enough of it.

To feed chickens acorns, first, leach the acorns to remove tannins.

Then, either sprinkle the crushed pieces over the ground while the chickens are feeding or mix them with their feeds to increase the nutritional value of their diet.

Again, if you plan to feed them acorns, you must leach them first. Below are the instructions to leach acorns:

How to Leach Acorns

Remove the shells and caps from your acorns before leaching them. Do not eat the raw meat of the acorns until you leach them first:

  1. Start by boiling water in two different pots. They don’t have to be the same size but large enough to hold all the acorns you have.
  2. Drop the raw, shell-less acorns into one pot.
  3. Let them boil for about 10 minutes or until the water darkens.
  4. Once the water is dark, strain the nuts through a colander.
  5. After all the water is drained, put the nuts into the second pot of boiling water.
  6. In the first pot, refill the water to a boil again.
  7. Repeat the process until the water boils clear. This may take about an hour or more, depending on the variety of acorns you have.

If you’re in a hurry to feed them to the chickens, you can use this other method to leach the acorns. It will take a couple of days, though:

  1. In a large container, pour cold water half full.
  2. Drop the raw shell-less acorns into the container.
  3. Let them soak in the water to leach the tannins out.
  4. Change the water when the color starts to turn darker.
  5. Repeat the process until the water no longer turns to a dark color.

This process will take a couple of days to remove all the tannins from the acorns.
