If your cockatiel doesn't want millet anymore, you can always give it sweet, juicy pieces of fruit or some treats at your local pet store. If you don't know what and what not to give your little bird, you can always search it up online, but i've already done some research for you.
You can feed your cockatiel grape nuts, unsalted popcorn, animal crackers, plain cereal, AviCake, and NutriBerry, Apples ,Pears, peaches, bananas, berries, kiwi, pomegranate, grapes, raisins, carrots, potatoes, beets, broccoli, legumes, frozen mixed vegetables, kale, greens (not lettuce), greenpeppers, zucchini and other squash, asparagus, ripe tomatoes, dried hot peppers, sprouts-bean, alfalfa, spinach,brussels sprouts, and bean sprouts.
Good Luck with your cockatiel!!!
I was eating some chilli and lemon crisps today and my cockatiel kept flying over. I wondered what she was trying to do and when I realised I tried my best to keep distance between the two but he somehow took a bite out of one I was holding. I completely freaked and took it out if his mouth and kept pinching his beak with water to wash it out slightly. I'm scared it's bad for him. He keeps flying over and trying to get some. Keep in mind these are slightly spicy, only slightly but can I gave him a piece of one or not. Also I rthink he's getting quite bored if mullets and stuff. Any idea what things I can give to him.
