During incubation, birds often leave the nest to forage for short periods leaving incubating eggs behind, resulting in a phenomenon known as periodic cooling. You can store for 10 days after they have been laid before hatch rate decreases (50% hatch rate is a good rate). As chicks are sensitive and have a weak immune system, cleaning and maintaining the hygiene of a chicken brooder is a top priority for the owners, and they should be well aware of how to do so. The odds are against refrigerated eggs hatching if they are later incubated but they can and do sometimes produce healthy little chicks. Incorrect readings will result.

Care must be taken to maintain humidity during the hatching period. If they're kept in ideal conditions, some authors Gail Dammerow, for example(1) considers it possible that they will remain viable for up to three weeks. In the meantime she makes sure they're kept cool and dry. cold, and dry, but not too dry. Hatching eggs suffer from reduced hatchability if the eggs are not cared for properly. Just like we turn eggs in the incubator, we need to turn eggs that are stored for longer than a couple of days to stop the yolks from sticking to one side of the shell. She knows instinctively that she has to prevent the embryo sticking to the membrane inside the shell. 0000001464 00000 n at Mississippi State University, http://www.msstate.edu/dept/poultry/trouble.htm, Mississippi State University Extension Service, Analyst Jim Wyckoff shares an update on global protein news, Broiler Economics from Aviagen's Dr. Paul Aho.

Perhaps the incubator's not quite warm enough. Other research(3) suggests that storing fertile eggs for up to eight days has no impact on hatchability, but twelve days or more worsened the likelihood of a successful hatch.
