Can Chickens Eat Acorns? Yes, chickens can eat acorns as an occasional treat. However, they may have health difficulties when consuming such oak nuts a lot. So, feeding in moderation is a good practice. It’s because tannin toxicity is there that binds to proteins in chickens’ digestive system.
Get into this article for proper feeding tips. Also, I’ll share the potential harm hidden behind such healthy nutritious nuts. So, without further due, let’s get started!
Can Chickens Eat Acorns? Are Acorns Good For Chickens?
Yes, eating acorns is okay but they should only be fed in moderation. More specifically, don’t cross 5% of their diet while feeding such a nutritious treat.
However, the big culprit here is Acorns with tannins. This can lead to a number of health problems, including diarrhea, weight loss, and liver damage.
Actually tannic acid content varies among oak trees. Hence, it is generally considered harmful to the liver and inhibits the body’s ability to absorb iron.
But as a suggestion, just toss them into a creek and let the water take care of the toxic removal. After doing so, we watch the water for about three days, or until it stops becoming brown.
Acorns are an excellent source of fiber, fat, protein, and vitamins and minerals. That’s what chickens need! Acorns can be included in your regular diet as a supplement.
A true fun fact is they can’t open until you crack it in the ground. Look at the video to see how they enjoy eating acorns.
