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.
On the point of wrapping, many people have pointed out that if you are going to do this you might as well put the Brisket in the oven at 220 degrees F (105 degrees C) and finish it there. After all, you have better temperature control in the average oven than you do in a smoker.
