Incubating Your Eggs

1. How must I store eggs?
Your eggs need to settle for at least 24 hours if they came through the post. This allows the air
cell inside the egg to return to its normal size. Eggs should always be stored with the pointy
end down while they are "in the hold". It's a good practice to follow and it will help your
hatch!
If you receive eggs that are getting old, you may only let them settle overnight.
2. When is my incubator ready to start incubating?
