I have a cockatiel since it was young. It's been with me and honestly I don't know its age or if it's male or female. It used to be tame, but due to my busyness, I only put food and water for it and cleaned its cage, and didn't even take it out. It became scared, but the biting is not strong yet. It sings beautifully, and I have more than one video of it. I took a video today, whoever wants to see it can contact me on WhatsApp. The price is negotiable, and the sale is without a cage.
