How Should Fennel Be Given To Cockatiels? 

When offering fennel to your bird, here are a few things you should keep in mind:

  • Fresh is best: Fresh fennel is the best option as it is the most nutritious. If purchasing fennel from the grocery store, ensure it is not wilted or spoiled.
  • Prepare properly: Before giving fennel to a cockatiel, wash it thoroughly to remove any dirt or pesticide residue. Remove the top and bottom of the stem. Chop the fennel into small pieces so it will be easy for your cockatiel to eat.
  • Mix with other food: To ensure your cockatiel is getting a balanced diet, it’s best to give fennel in combination with various other foods. You can mix it with fresh foods like fruits and leafy greens, add in a few sweet potatoes and sunflower seeds, and make a lovely snack for your bird. You can also feed it with warm water.
  • Small quantities: While fennel is very beneficial, it should be provided in small quantities to the cockatiel. Too much of any good thing can negatively affect the bird’s health.
  • Fennel seeds: Fennel seeds are aromatic and sweet tasting. They are also extremely healthy for birds and help improve antioxidant levels as well as immunity. You can sprinkle them on several types of food items and seed mixes to give your bird a refreshing treat.
  • Fennel leaves: Fennel leaves are also safe for your bird. You can scrunch them up and add a couple of the bird’s food.
  • Cooked fennel: For juveniles, it might be better to cook the fennel a bit before offering it because they may not be able to digest it properly. You can boil or roast the fennel, but do not add salt or cook in excess oil.

How Much (And How Often) Should You Give Fennel To Your Bird?

When offering fennel to your bird, it should only be offered in small quantities as a treat. 

Serve a pinch of finely chopped fennel for baby cockatiels approximately once or twice per week, while adults may enjoy a small sprig of fennel once a week.

Monitor how your feathered friend responds to the new food before increasing servings to ensure it agrees with their digestive system.

Are There Any Dangers To Giving Fennel to Cockatiels?

While fennel contains lots of useful vitamins and minerals, it also has a fair bit of iron, and therefore it is best not to overdo fennel in your cockatiel’s food. 

Excess iron buildup in birds can cause iron storage diseases.

Too much fennel may cause lung-related afflictions, including pneumonia, due to the inhalation of essential oils released during chewing. 

Some cockatiels may have allergies or sensitivities to the powerful smell of essential oils in fennel seeds.

You can also offer fennel leaves to cockatiels

This could cause respiratory or digestive issues in the bird.

As with any new food you introduce to your bird’s diet, it’s always a good idea to start with a small amount and monitor your cockatiel for any adverse reactions before offering more.
