Temperature: The eggs need to be kept at 99.5 degrees at all times; just one degree higher or lower for a few hours can terminate the embryo. Humidity: 40 to 50 percent humidity must be maintained for the first 18 days; 65 to 75 percent humidity is needed for the final days before hatching.
How do you set eggs in an incubator?Eggs are placed in incubator in one of two ways, either by placing them on their side or by placing them with the round end up.

Do birds fertilize eggs before or after they are laid?
Eggs are fertilized internally before they are laid, so an egg already laid by a single female bird cannot be fertilized. If it occurs, fertilization happens early on in the oviduct, before the yolk and egg white are coated onto the ovum, as the cells of the ovum are dividing.
Do birds need to mate for each egg?
Birds of all types, from parrots to eagles and falcons, are monogamous. Usually, the parents take turns incubating the eggs. Birds usually incubate their eggs after the last one has been laid. In polygamous species, where there is more than one mate, one parent does all of the incubating.
