Pretty much all kinds of birds lay unfertilized eggs, some lay eggs more frequently than others. For a cockateil it is a common problem , they exhaust themselves by laying infertile eggs or becoe egg bound. Naturally all birds lay eggs consistently.
Generally Females are little bit heavier at the time of laying eggs , but it is not visible from outside , because the feathers are giving shape to a bird so it is not that much visible.
Birds naturally take 12 days to build their nest , on that time they are carrying their eggs . They lay one egg per day for 3-4 days. then 12 days incubation period and then after another 12 days the eggs will hatch and chicks came out after that they remove their nest .

It is easy to maintain the warmth in a incubator , just set the temparature and the incubator will do it by itself, but in the wild there is some certain situtaions , where weathers are different and predator's fear are always there, thats why into the wild the eggs may not get enough temparature for fertilize.
