Well, if parakeets are healthy and happy both male and female will chirp alot. That being said, male and female parakeets will often screech if they are not happy or if something like your music being played too loud or a cat is bothering them.
Your parakeets may have not been male and female they might have just been 2 females or 2 males.
both male and female
By there noses. A males nose is blue. A female is pink or a light peach
I don't think so. I read that adult female parakeets noses are brown and that adult male parakeets noses are blue. But, young female parakeet's noses are "bluish" and a young male parakeet's nose is pink.
There is not a set number of years that a male parakeets sperm is not good anymore. A female parakeet can store a male parakeet's sperm for up to 10 days.
yes
You will know when your parakeets (male and female only) want to mate when they start to get along with each other. The male will start to respect the female and began feeding her. This is also a sign for breeding. Enjoy breeding your parakeets! Trust me, it's a LOT of fun!
It depends, if they r both females, no unless its the babies mother and yes if they are both male or if one is male and the other is female. But sometimes parakeets only like the parakeets they think are pretty so its kind of anonymous.
He feeds her the remains of his last meal out of affection!
u could either remove 1 of the females or purchase another male.
Absolutely. Parakeets like to bond and males will fight for females if there is not one for each. But in your case, there are more females than males, which means that eventually each male will bond with a female and the lone female will, I guess, be alone... Female parakeets don't usually fight each other for male parakeets, unless a female that is alone tries to steel a male that has already bonded with another female,(not likely to happen). It also depends if you are planning to breed the parakeets, if so then you might have a problem. The lone female might go inside nesting boxes and smash the eggs. This happens because a female will get(hard to believe) Jealous, to solve this you might want to consider getting a ale for her to bond with. If you do get another male, put the one female and the new male into a separate cage for about 3 weeks. This should be long enough for them to bond, after the 3 weeks put them back into the original cage and they should be fine. If they don't get along though and you don't want to return the parakeet, you can replace that male for one that has already bonded with a different female. If you keep the lone female and the replacement male together, he will eventually bond with her. And the new male that you put in the original cage will eventually bond with the female who had her mate taken away from her.
