Well, darling, parakeets aren't exactly interior decorators, so keep it simple. Line their nest with clean, dust-free materials like shredded paper or coconut fiber. Just make sure it's cozy and comfy, like a little birdy paradise. And for heaven's sake, don't go overboard with the bling - these birds are all about comfort, not luxury.
Petco and Petsmart has them
yes
a box
I don't know any animal that is really fussy about where to have sex - including parakeets.
The parakeets will lay their eggs in a nest that they build themselves. The parakeets will sit on the eggs until all have hatched. The eggs should hatch after 18 days.
Parakeets (and parrots/budgies in general) only need a nest if you intend to be breeding them. Otherwise they do not need one and you should probably not provide it or they may begin to act like they are nesting and ignore other activities.
There are Monk Parakeets in the trees near the entrance to the zoo. They have a large nest, and visitors can see it.
They can,yes maybe its a dud? Or maybe somethings wrong with the egg?
Yes, Parakeets love to have company in their cage, two mail parakeets would be fine together.
you do not need to give them any material the mom and dad will pick off some feathers and put them in the nest for the eggs to be you can try and give them something but they might not take it.
Yes
if you really want them to go in, its very simple, just grab them one by one from the top of their legs with both hands, touching their belly's, so they won't scratch you, and put them into what ever you are going to put them.
