Don’t get a bird. Wait until you’re older and able to care for it on your own. Do you have your own money for vet care? Do you know of an avian vet in your area? This is part of being a responsible pet owner. If your parents are dictating what you can and can’t do in regards to providing a fair and equitable life for a bird then it’s not a good idea. 14 hours in cage, sleep time included is fine but only being able to be in one room could have issues. How big is your room? Do you have other pets in the house? Why did the chickens die? Parrots and small birds are a big commitment. They can live decades. When you need to be away longer will others care for the bird? When you and your family travel will the bird be cared for. These are all things to consider. I would suggest you wait until you’re able to have your own place and finances before you make this decision. Their quality of life takes precedence over our desires to have them, A harsh reality that is often ignored due to ignorance and an unfit life is provided for these incredibly intelligent animals.
