Fertilised platypus eggs stay in the mother's body for around 28 days. The egg is incubated by the mother curling around it and keeping it warm and dry in the chamber of the burrow for another 10 days.
78-83f
They don't give birth - they lay eggs, which need to be incubated at a suitable temperature.
Parrot eggs are either fertile when they are laid or they are not fertile when they are laid. They have to be fertile and properly incubated in order to hatch.
21 days, give or take a few days.
Turtles lay eggs which, depending upon weather conditions, take from 45-90 days to hatch.
While gathering eggs to be incubated you need to keep the eggs in a cool, humid place. You do not want or need to refrigerate the eggs, just keep them under 60 degrees F. You will also need to keep the humidity level as high as possible without wetting the eggs. Do not gather for more than 7 days as after this time even well stored eggs will lose viability.
The platypus, one of only two types of mammals that lay eggs, has a duck-like bill, or extended snout, which is not actually a beak. The animal was commonly referred to as the duck-billed platypus.The bill does not open as a bird's beak does, the mouth being on the underside and the nostrils on the front of the upper side.
It depends on the type of fowl you are trying to hatch. Chickens eggs should be incubated at 100 degrees Turkeys eggs should be incubated at 99 degrees Ducks eggs should be incubated at 100 degrees Geese eggs should be incubated at 99 degrees Guinea Fowl eggs should be incubated at 100 degrees
No, fertile hen eggs need to be incubated at the proper temperature and humidity levels to hatch successfully. Simply sitting in hay will not provide the ideal conditions for the eggs to develop and hatch.
The only mammals which lay eggs (monotremes) are the platypus and the echidna. These two monotremes lay soft, leathery eggs. The eggs will keep out water to some extent, but they are not watertight. Nor do they need to be - both animals incubate their young on land, not in the water.
You can't, sorry. :) any eggs that are still little and need to be incubated can just be deleted directly from your inventory. But you don't get any XP when you do it this way, so...
You don't. They do not need it.
