Dangerous impact of Acorn on Chickens

  • Poisonous

Toxic exposure to Quercus can cause symptoms similar to those of oak or acorn poisoning. Cattle as well as other farm animals often ingest this toxin. Oak trees, leaves, & nuts all contain tannins, the active ingredient in Quercus poison. 

If not treated properly, it might result in serious organ damage. Toxic effects from Quercus include: 

  • Insomnia

Its symptoms are very similar to those of food poisoning. If the chickens exhibit these symptoms & you suspect they have eaten acorns, take them to the vet immediately. Their organ systems can fail from extended exposure to tannic acid. 

  • Trauma to the Rectum 

Ingestion of tannic acid poses a threat to the chicken’s digestive system. Diarrhea is a common sign of the illness. Rectal tissue can also be badly destroyed if the chicken’s intestinal system is constantly disrupted by diarrhea. 

Chickens can get kidney abscesses & tissue scarring from this. The chicken may become critically dehydrated due to diarrhea. 

  • Injury to Organs 

Organ damage is a potentially lethal effect of tannic acid. One of the very first organs that get attacked is the digestive system. Food poisoning-like symptoms will appear in the chicken. 

However, the kidney and as well as liver are also at risk if tannic acid is found in the systems on a regular basis. Kidney failure can occur if the kidney becomes enlarged. The chicken’s lack of an internal filter mechanism makes this extremely dangerous. In addition, liver failure threatens life. The chicken could die if this isn’t treated right away. 

The Best Way to Guarantee the Chicken’s Health When Feeding Them Acorns –

You may take precautions to make acorns safe to consume even if they contain compounds that can be harmful. Acorns’ tannic acid can be neutralized by first washing and then boiling them. It softens the nut so that birds may more easily chew it. 

Leaching is frequently used to get rid of tannic acid. The acorns must be leached properly: 

  • The acorns need to have their shells and crowns removed. The nut on the interior ought to be the sole component left. 
  • Prepare two pots of boiling water. If you’re going to put acorns in water, the water should be boiling hot. 
  • Turn the heat up high and add the acorns after the water begins to boil. 
  • 10 – 15 minutes is how long you should cook the acorn. There are other compounds being flushed out with tannic acid, which is why the water turns dark. 
  • The acorns should be strained after boiling. 
  • Reheat it in fresh water and bring it to a boil. The acorn boiling process should be repeated until clear water emerges. 
  • This procedure can be time-consuming and costly. Fuel and water storage facilities require a lot of electricity. On the other hand, this process makes acorns safe for the hens to eat. 

Those who find this procedure time-consuming have the option of switching to the cold-water approach. The steps to the cold-water version are: 

  • Submerge the acorns in the ice water. 
  • Acorns should be soaked to remove the tannic acid.
  • Water should be changed when it becomes murky. Steep the acorns & keep changing the water till it becomes clear. 
  • The cold-water method requires less manpower. However, the water could not clear up for several days. It’s also not as efficient as boiling water would be. 
  • The acorns will be completely safe for the chickens to eat once you’ve taken these measures.
