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.
18-21 days
It depends what animal it is.
30 days
Female red-eared sliders typically lay eggs about 2 to 4 weeks after mating.
I do not think you can. My parakeets had eggs and they did not hatch because she did not take care of them right. If they do have eggs you may take them away and sell them or kill them.
Maybe a couple of days. When it is ready the shell cracks a little bit everyday :)
Female dogs do not have mature eggs waiting for fertilization like some other animals. Instead, the eggs are released during the female's heat cycle, which can happen in response to mating. Once released, the eggs can be fertilized by sperm from the male dog.
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).
In canaries, after mating, the female typically lays eggs about 5 to 7 days later. The eggs are usually laid one at a time, with a clutch consisting of 3 to 6 eggs. The entire process from mating to the first egg being laid can take around a week. After laying, the female will incubate the eggs until they hatch, which usually occurs about 13 to 14 days later.
the male sea horse has a pouch that it uses to carry the eggs, when mating the female gives the male 1500 eggs
nope. sometimes females will lay eggs even if no male is around. they're not fertilized, though.
