Hi Shanthala,
When you try to introduce birds to each other, it is a long, gradual process. First, the new bird should be quarantined in a different room for at least 45 days in case it has any diseases. Then, you place the birds’ cages side by side so they can see each other and interact through the bars if they want to. If they start to show interest in once another by always sitting near each other, and vocalizing back and forth, then you can try them in the same cage. This should always be done with supervision, and often just a few hours a day for a week or so before you leave them together over night. You need extra food and water at opposite ends of the cage so one bird can’t prevent the other from eating or drinking. A small amount of harmless sparring is normal, but chasing, biting, pulling out feathers or drawing blood is not a good sign and the birds should be separated immediately. Some birds are simply not compatible. They don’t care for the mate we choose for them. There is nothing you can do about this other than to keep them in separate cages.
Since you probably do not know anything about the male bird, this makes it even harder. He may be an old bird who is set in his ways and doesn’t want another bird in his cage. He may be breeding age and the female is too young, so he attacked her for not being receptive to him. If the female is not at least two years old, she shouldn’t be caged with a male anyway. A female cockatiel will lay eggs at too young of an age if she is paired with a male too soon. If she isn’t 2, then you should not try to cage them together until she is. Even if you don’t plan to breed them, she will likely end up laying eggs at some point, with or without a male. Possibly when she is older he will be more receptive to her.
Thank you for asking Lafeber,
