Yep.
I don't know any animal that is really fussy about where to have sex - including parakeets.
Yes, yes they will.
Parakeets do not mate for life. They are monogamous during the breeding season, but they may choose different mates in subsequent seasons.
If they have a mate, yes, unless their human purposely separates them from their mate, the mate dies, etc.
a box
They mate or do a jig then they lay the eggs and sit on them
They mate.
yes withouth a doubt
budgies and parakeets dont mate they do not need a male to lay an egg so the answer is no season
It's impossible to tell for sure. If he does it will take 3 months to a year. Also parakeets often die shortly after their mate or companion dies. You should take it to the vet to have him checked because grieving parakeets are very susceptible to illness. Sometimes parakeets will die from grief and no other reason can be found wrong. My close friend had two parakeets, and after the female died suddenly of egg-binding, the male refused to eat or fly or do anything. All he would do is lie in the cage in the spot where his mate had died, and if he was moved he would go back to that spot. My friend took him to 2 avian vets who could not figure out what was wrong, no infections or tumors or anything like that. The vet gave her vitamin food to feed him. She hand fed him for a while and then he died anyway.
You shouldn't because the male will mate with one of them and parakeets hate being lonely and the other one will be left out....
You can not. They have to choose to be mates for what the other one does. Kinda like we do. Also, they might be the same gender.
