Not necessarily. You can breed them in any cage.
yes
This is an excellent website just on parakeets : http://parakeet.yolasite.com/ It talks about how to care, breed, and train your parakeets.
it just means that she is ready to breed
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!
What is the temperature of parakeets drinking water
Well, Parakeets breed in the beginning of Spring and Fall. As an example, I'm going to use Fall. On the first day of Fall (September 23 *2010*), would be the best time to put in the nest box. Maybe even earlier. Then, you should waite about an exact month. (My Parakeets mated after an exact month). Which would be October 23. Around those days---October 22,23,24--- your Parakeets should mate. You should at least waite a week (Example: October 22-29).
They are 2 different species. I doubt they would breed. Would parakeets and cockatiels breed, NO
They will breed if they want to. Most likely in the breeding season. Hope this Helps:))
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.
