Hey can anyone help me? I just bought 2 cockatiels and this is my first time rearing a bird...so i don't really have any experience. Anyway, they are doing pretty fine, they look healthy but whenever i go near them, they start shaking and when i open the cage gate, they start going crazy. Any suggestions to try to bond with them? By the way, can you tell how old the cockatiel is without its band ring?
