Underweight Cockatiel: When Should I Be Worried?

Underweight Cockatiel

If your underweight cockatiel or pet birds falls outside of the standard weight range, you may need to take steps to help them gain weight. Some reasons for cockatiel losing weight or being underweight include poor diet, depression, genetics, and behavior when eating. As a caretaker, you can improve their health by helping them put on some additional pounds.

Underweight Cockatiel

Rework on the cockatiel weight chart

Cockatiels are finicky eaters, and they prefer less healthy food in their diets, which can cause their calorie intake to drop. When the weight of a cockatiel drops, it indicates that he is skinny cockatiel , deficient in protein and fat and is considered as an underweight cockatiel.

This cockatiel gain weight technique worked because I refused him the option to select other foods whenever peanuts were offered. He eventually liked having peanuts. You should provide them with a variety of sunflower seeds, red palm oil and grains, as they will appreciate them and acquire enough calories from them. They will eventually gain healthy weight.

Control the activity level if your cockatiel is hyperactive

Cockatiels can get stressed and even lose weight if they’re constantly active or pestered by other birds. If your cockatiel is too high-strung, try controlling his activity levels by restricting his space and removing toys from his area. This will give him a chance to relax for a while, which can help increase weight due to the carbs content in his body.

Separate from other birds and give attention

Aside from proper diet you need to do is isolate him, especially baby cockatiel and handfeed him for a short while. Although it can be taxing, seeing him rapidly gain weight is beneficial for his mental state.

Although it may not be possible to keep cockatiels apart from other birds permanently, doing so temporarily can be beneficial since you would then know what his wants and health issues are. Also, take note of the health conditions of other cockatiels as well. One sickcockatiel can quickly spread its disease to others through contact. This is something else you should keep in mind before separating them.

Increase in food quantity

A cockatiel needs 2 tablespoons (~30 grams) of pellets or seeds twice a day. In addition to a solid diet, you should also give him access to water at all times.

If your bird is underweight, it’s best to feed him 3-4 tablespoons (~45-60 grams) of pellets or seeds each day. This will not only provide the energy he needs to stay active but help him gain weight more quickly.
