To use this Hagen cockatiel seed, simply fill your bird's feeder with an appropriate amount. Check the feeder daily and refill it when it's getting low. Make sure to clean the feeder regularly to keep it hygienic. When it comes to storage, keep the seed in a cool, dry place away from direct sunlight. This will maintain its freshness and nutritional value. As for feeding, you can offer it as a staple diet, but remember to alternate with Hagen treats to add variety. If your cockatiel starts being choosy about the seeds, start using a vitamin supplement like Prime as recommended on the label. Keep an eye on your bird's health and behavior, and if you notice any changes, consult a vet.
