Fertile eggs will begin to hatch about 18 days from the date the female BEGINS incubating the eggs, which usually occurs with the second egg laid. Incubation is when the female sits on the eggs most of 24/7 (she'll come out of the nesting box to defecate, drink, and maybe eat, although the male feeds the female most of the time while she incubates the eggs/cares for the babies).
Since it's past 18 days for the first and second eggs laid (they probably aren't fertile), you don't start counting 18 days for the last egg until the last egg is laid. In other words, 18 days for the last egg laid isn't up until around 24 Sep, so there's still a chance the 3-5th eggs might hatch. It could be that none of the eggs laid are fertile/will hatch. Once any eggs hatch, the parents will care for the babies. What happens next depends on what your intentions are for the babies. If you hope to sell them or give them away, you'll need to handfeed them with baby parrot handfeeding formula and a handfeeding syringe in order to make them tame enough to make good pets.Any fertile eggs will hatch in the order laid, usually one every other day. Some adult birds push an emerging baby to the side to facilitate hatching, some keep the emerging baby under them while still sitting on the other eggs, some birds will keep an emerging baby half under them/half not under (a baby still has to be kept warm through the hatching process, which takes 24-48 hours). You should let her abandon any unhatched eggs on her own. If you remove eggs before she abandons them, she may continue to lay and lay, which isn't good for her health. When she realizes they won't hatch, she'll abandon them...you can then remove the eggs and destroy them.
