remove her from the cage then remove egg
The cockatiel does not need a nest for sleeping. Nests are not used for sleeping, they are strickly a breeding/mating thing. DO NOT put a nest in a cage with a female cockatiel as it will make her produce unfertile eggs and could cause her a great deal of harm.
Two of them is being solitary it helps the male eliminate the competition for the female. And being aggressive so they can defend their territory. i hope this was help(:
Eggs are obtained from female birds, such as chickens, by laying them. The eggs are then collected from the nesting area before being cleaned and prepared for consumption or sale.
Just guessing here. There are bad birds sometimes, just bad wiring. The odd of you getting two of them, slim. Birds tend to get aggressive for a reason. Very often from not being handled enough. Are you treating the new one the same way you did the old one? They have to be handled properly for them to trust you. Are their wings clipped? That tends to subdue most birds.
Yes this is fine. Cockatiel's are quite happy being pets as long as they receive a lot of attention. However, a companion is usually much appreciated by your cockatiel whether he or she mates or not.

No, it is not recommended to house female bettas with parrotfish. Parrotfish are aggressive and can be territorial, which could lead to stress, injury, or even death for the female bettas. It's best to keep them in separate tanks to ensure the well-being of both species.
that depends whether you have a male with her or not. if you have that's a pretty good sign that she will lay eggs soon. Cockatiels are birds. They do not get pregnant, as reproduction is done through the laying of eggs. The eggs take about three weeks to form properly in the body, but this is not called "pregnancy". Chances are high that your cockatiel may just be keeping herself occupied. Being curious and intelligent birds, they need something to do. If there is no male with her, give her plenty of bells and toys, and other items to "chew" on. If there is a male, she may be ready to breed, so you should try and provide her with a nesting box.
Just leave it in the cage. If it's not fertilized she should figure that out soon enough and not care, then you can take it out.
Either the male has built a bubble nest to prepare for breeding, or they are being aggressive towards each other and it's a way of being able to fight.
because you're there in front of him being passive aggressive? how does he know when you're being a swan?
