You will know when your budgie birds are ready when the pair start to be more active. A male will feed a female and they will tap the beaks together. Just know that a female budgie will be ready when she has a brown/tan color above the beak. (you must have a nest box for the bird to lay her eggs.)
It is pretty obvious. If you have a male-female pair, they start courting: cooing to one another, "beaking", sharing food, regurgitating food and sharing it, preening each other, doing head-bobs (more often males to females). Most parakeets need a nest box to trigger mating.
Parakeets are parrots, and parrots are birds. Birds 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". They look the same when they are laying eggs as when they aren't. In other words, birds don't "hold" their eggs inside their bodies and show a big belly to indicate that eggs are on the way. The egg shell is the last thing that develops right before the egg is laid, therefore, a hen doesn't "show" in the sense that human women "show" when they are pregnant.
Birds which are getting close to laying an egg become more lively, excitable and playful, not listless and quiet. If they have a nesting box, they will spend a lot more time in the box, preparing it for nesting, and possibly being very protective of that area. If there is a male, he may start feeding the female.
A parakeet with a swollen abdomen is not a sign of a bird about to lay an egg. It is either eating too much of a high-fat diet (common among birds with a seed-only diet) or it has a tumor.
Swelling in the abdominal area could also mean the parrot is egg-bound, though this tends to present more as swelling near the bird's tail, near the cloacae. She will be distressed and show signs of constipation, be reluctant to move and "waddle" like a penguin. If your bird shows signs of being egg-bound, she must be taken to the vet as soon as possible, as this can be a life-threatening condition.
Many birds have a human preference. Maybe it's your best friend, maybe it's your dad or your spouse, but parakeets do pick and choose who they like. Parakeets may attack your hand and bite, or maybe squawk when you come too close. Those are signs that your parakeet may not like you. But to be sure, call up a friend and invite them over. Have them do hand exercises outside and inside your parakeet's cage. If your parakeet reacts the same way, it may be hand shy. Try people with opposite genders or different ages. Your parakeet may find someone it likes. If not, research on how to tame a parakeet with NO BITING. Or consult a veterinarian. They may have suggestions on how to tame a hand shy parakeet.
You'll know they have mated if/when the female lays an egg. Otherwise, there's no way to know unless you see them mating.
Probably when they are very affectionate with one another or you have baby parakeets.
they will preen each other and feed each other and will not want to be seperated!
If they have babies.
Fertile eggs
You'll know when your dove has mated if you hear sounds that your dove hasn't made.
Yep.
there fat
well it depends if she mated with 2 different dogs then the puppy would look like its dad(the 1 she mated with). but if they were the same i don't know
YOU dont THE BIRDS know
I don't know any animal that is really fussy about where to have sex - including parakeets.
8 months
yes anyone can have a parakeet anywhere I'm pretty sure i know people who have parakeets here Yes they do!!
Don't know read a book
don't know but that would be funny
you Will know if parakeets love each other because one will regurgitate seeds into the others mouth. usually the male is the one to regurgitate the seeds into the females mouth
