I need help! So I bought my old budgie (who had now been with me for 1 year) a new budgie and he is being aggressive towards me. He is NEVER like this. Me and him have such a strong bond and he never acts like this. Now it’s attacking me and biting me when I come near his new friend. Anyone know...

so my cockatiel, jupiter, is 1 year and 5 months old already and still doesn’t understand the concept of toys. how can i introduce them to her and what type of toys would be good for a bird with no experience?
