The eggs will always hatch in the order they were laid. Usually after 18 days, the first fertile egg to be laid will get hatched and thereafter one egg will hatch every other day. Do not get alarmed if you see the mother pushing the chick to one side of the nestbox. This is done some times by the female parakeet. It is done to facilitate the hatching of the remaining eggs.
With the brisket prepared you need to get the smoker ready. You will want a fire of about 200 degrees F to 230 degrees F (95 degrees C. to 110 degrees C). At this temperature, you can expect the cooking time to be about 1 1/2 hours per pound.
Before the brisket hits the smoker it needs to be rinsed in lukewarm water, patted dry with paper towels and be at room temperature. If you are going to marinade it should be done for at least 12 hours before you smoke. If you are going to apply a rub it should be done about 30 minutes to an hour before you smoke.
