The nutrients found in cauliflower are the following:


We have already established from our previous topics that chickens definitely need the right amount of calcium in their body. They do not just need it for the development of their bones to grow, but they most especially need it for when they are laying eggs. 

Often, chickens start to lay soft eggs due to calcium deficiency. However, cauliflower cannot alone provide the calcium your chickens need but are a good addition and boost. 

CChickens also need an ample amount of vitamin C, especially during the cold season. This is where they are more prone to getting ill by being infected with various poultry diseases

Folic Acid

Your chickens can get a lot of benefits from the folic acid found in cauliflower. It is a nutrient a chicken must-have, especially for laying hens, as it assists in making the reproductive stronger and helps produce healthy eggs. 

Another thing folic acid is good at is how it helps in the formulation of a red blood cell. If your chickens have healthy and robust blood cells, then your chickens will never have a hard time regulating the right body temperature but can also maintain the flow of oxygen very well.

Iron can also help in maintaining the blood circulation of your chickens. Most laying hens need enough iron in their bodies as they are at a higher risk of having anemia. However, the chicken layer pellets or feeds you have been giving them are already enough as it contains ample amount of iron. But, it will not be a problem if you give them tidbits amount of cauliflower treats sometimes do not overfeed them with it.


Magnesium helps vitamin D to become functional. It assists in forming vitamin D for the body to metabolize.


Apart from calcium, phosphorus can also make the bones of your chickens stronger and better. Cauliflower is rich in phosphorus as it contains the nutrients your chicken need to have solid eggshells. 


Chicken owners who have joined the bandwagon give their chickens some cauliflower treats more frequently during the warm season. Cauliflower also contains potassium a chicken needs as it helps them to prevent suffering from dehydration.

Vitamin B6

A cauliflower is undeniably high in Vitamin B6, and you have no other reasons why you should not feed them cauliflower. Similar to magnesium, where it lends itself to other vitamins and minerals, Vitamin B6 has the same role.

Vitamin B6 helps the hens in processing and breaking down all the proteins it ingests. The body cannot absorb and at the same time metabolize all the proteins without the assistance of Vitamin B6.

Vitamin K

Rich in Antioxidants

One of the good sources of antioxidants is cauliflower. You can feed this to your chicken to keep them healthy.
