Now that we have addressed this question: Can chickens eat tuna? We will discuss how you can feed tuna to chickens. Chickens can eat both fresh and canned varieties of tuna. 

You should avoid feeding your chickens canned tuna or tuna that is seasoned in oil, as this can make the birds sick.

Which Tuna Varieties are the Best for Chickens?

There are wide varieties of tuna; unfortunately, not all are healthy for chickens. Skipjack tuna is the best variety of tuna you can feed to your chickens, and this tuna has a low mercury content and is safe to consume for chickens. 

Are There Any Risks of Feeding Tuna to Chickens?

While chickens can eat tuna, there are a handful of risks you must consider before giving the fish to your birds. The biggest risk is health problems associated with processed food items and mercury contamination.

Mercury is an element that occurs naturally in certain environments worldwide. Human activities such as mining and coal burning release mercury into the atmosphere, eventually ending in the water. 

Fish absorb the mercury in water, and chickens consume mercury when they eat tuna or other fish species. Mercury can cause many health issues like heart disease, developmental delays, and neurological problems. 

You should ensure that you feed the chickens tuna occasionally. You must also remember that tuna is processed food, and most processed food is artificially altered from its natural state. 

Processed food contains several dangerous chemicals that can harm the chickens’ health.

Processed food is less nutritious than whole foods, so it should comprise a big portion of the chickens’ diet.
