The cere, a patch of skin around the nostrils, is blueish in males, pink in females.
a boy.
So the male Parakeet has a blueish cere, and the female has a pinkish brown cere. Here is a bad picture of what it kinda looks like
you can go to a vet but they will probably say they are to young to tell. you will have to wait until there cere matures to the respectful color
No. They are abot the same size.
A male parakeet has a blue nose above its beak.
For the rare parakeet it is quite simple - if the nostrals are blue - it is a boy. if the nostrals are pink, red, or brownish - it's a girl.
No! I think that answer is obvious. Boys do not lay eggs. Fact of life.
Sure
It is very difficult to determine the gender of a budgie when they are young. Wait a couple of months until they grow. Then if it turns into a brownish colour then it will be a girl, if it turns a bluish-purple colour than it will be a boy.
To tell for sure, you have to get it DNA sexed. Any avian vet will do this... in Canada, it is usually around $25. Not all parrots can be visually sexed like eclectus parrots, cockatiels or budgerigars...
You can tell that your parakeet is old by looking at the rings on it's head. If there are a lot of black rings that go around it's head, it is younger. If your parakeet has little rings unlike this one, it's older. This parakeet has almost a white head which means it is older.
It's a young boy.
