When the reaction is complete, the endothermic gas must pass through a gas cooler (h) which uses ambient air or water to bring the temperature of the endothermic gas below 300 ÂºF. The gas must be cooled quickly to prevent undesired chemical reactions that create carbon fallout.
If you only have a few hens and need to wait a few days or weeks to collect enough eggs for your incubator, then keep them around 50-60 degrees and 75% relative humidity. (Best hatch rate is with eggs stored less than 1 week.) Do not put in refrigerator. Put them in an egg carton with the big end of the egg up.hicken eggs are incubated at 99 to 99.5 degrees. Chicken eggs incubate for 21 days. Your countdown for days starts when you put your eggs in your incubator. It does not start when the hen lays her eggs.
Rating Newest Oldest. Best Answer: Nesting: Two broods of 3-5 blue-green eggs with a 12-14 day incubation period. Fledging occurs 14-16 days after hatching. The nest is a mud cup lined with soft grass and reinforced with grass and twigs. The nest is usually placed in a tree, on a ledge, or on a windowsill. http://www.bird-friends.com/BirdPage.php... So they will hatch 12-14 days after the mother began incubating the eggs, and the babies will be fledging (leaving the nest) about 14-16 days after that. Remember, though, that when they first leave the nest, they will not yet be flying, so you need to be careful of any pets or children that may be in the area.
