No, but don't be surprised if your budgie shows you sexual signs after they have bonded with you. It's a completely normal thing and don't be alarmed. You'll see them "humping" their favorite toys or even your arm, and they have the tendency to regurgitate their food on items they love too, including you. ;)
Yes, yes they will.
Yep.
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
I don't know any animal that is really fussy about where to have sex - including parakeets.
budgies and parakeets dont mate they do not need a male to lay an egg so the answer is no season
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....
Pets do not typically mate for life. They may have multiple partners throughout their lifetime.
