I don't know why your mom doesn't want to let them out of the cage. I personally think it is cruelty to confine birds to a small cage. Its like someone locking us in our small bedroom for the rest of our life. What a sad life we would have. For my birds, the cage is nothing but a bedroom and a dining room, used for nothing but to sleep and eat/drink. If they are not sleeping or not eating, they are almost never in the cage. Their cage door is open at all times so they are free to go in and out as they like. We only lock them in the cage when we are not at home, for their own safety, but that is usually just for 3 hours at the most. If we forget to unlock their cage in the morning, they bang their head against the door and cry to make us open it. You should really convince your mom to let them out of the cage. Tell her its important for their health and mind. They need exercise and they need the freedom they deserve. If she doesn't want to clip their wings, many birds do well out of their cage with unclipped wings. My friend's parakeets know exactly when to turn and where and they enjoy flying around the house a lot. They never crashed into walls and windows once they learned the directions of the home. If their wings won't be clipped, its important they be under supervision while out of the cage, for their own safety. Even if you choose to keep them locked in the cage (which I wouldn't do) at least give the 2-3 playtimes in the day in which you let them out to play, exercise, and have fun. I personally think your birds can never be the true companion and friend waiting to get out and love you, if it is never getting the chance. Birds are very friendly and loving pets, and they become great companions, but they need to be interacted with, and allowed out of the cage for them to show you, what great pets they really are. Give your birds the freedom they deserve and keep an eye out for hazards (open windows, doors, ceiling fans, kitchen hot stoves/oven, open toilets, chemicals, etc.) if you allow them to "fly" in the house. The safest way to provide them with freedom is to clip their wings. I've only clipped my birds' wings twice in the 3 years I have them because they got so used to roaming the house of foot, that they don't fly at all now anyway. They don't like to fly and even when they want to get off the sofa, or some high furniture, they call me for help. Lazy little birds. LOL! If I don't help them, they end up flying down, but they act like they are scared to fly.
