Collection & Storage of Eggs
Choose eggs that are of good size, not abnormally big or small. Do NOT set dirty, cracked, or porous eggs.
Clinical studies at the University of Arkansas have shown that if your going to set a dirty egg, set the dirty egg,
DO NOT SAND, WASH OR WIPE dirty eggs as hatchability decreases with these practices!
ALL ABOUT WASHING EGGS! CLICK on.... post #10836
Cuticula is the thin membrane that covers the whole eggshell that is made from the sticky fluid when laid which covers it and quickly dissolves due to carbondioxyde activity.
This membrane can be penetrated by gasses but functions as a kind defensive mechanism to prevent the entry of bacteria.
The washing and rubbing action also serves to force disease organisms through the pores of the shell. Place the eggs upright in an egg carton with the FAT, air cell end of the egg UP! Allow eggs to sit in a moderately cool, somewhat humid place for storage. Basements are great. Moderately cool means 55-65 degrees. Rotate your eggs a 3 times a day to keep the embryo from sticking. An easy way to turn all of the eggs at once is to place a thick book under one end of the carton, and later remove the book and put it under the other end of the carton, 3 times a day. Before adding eggs to the incubator always WARM eggs UP slowly to room temperature. IF THE EGGS ARE COLD Condensation can cause bacterial growth on the eggs! You can collect eggs up until 10 days or so, but after the 7th day lower hatch rates may result.
Stored eggs take longer to hatch (about one hour per day of storage).
It is important to ALWAYS wash your hands before handling your hatching eggs!
Omphalitis, yolk sack infection is caused by a bacterium that enters through the porous egg shell and easily kills embryo's and newly hatched chicks. Unfortunately, incubation conditions are ideal for breeding bacteria as well as incubating eggs. For more information on storing eggs refer to Recommendations for hatching egg handling and storage
Now if you MUST store hatching eggs longer, store in same cool conditions as above, set SMALL END UP to avoid water loss, PH changes etc, see plastic bag storage below. There is much more info should you research storing for long periods.
When eggs were held in storage, the small-end-up pack position without turning, their hatchability was equal to or better than that of eggs packed small-end-down. When eggs were stored in the small-end-up position for 2 to 4 weeks, it was, not beneficial to turn them daily as had been previously demonstrated to be advantageous for eggs stored small-end-down. Thus, the inconvenience and expense of daily turning can be avoided without loss.Evidence is also provided that hatchability was equally good whether eggs were stored on their sides and turned through 180° daily or stored small-end-up without positional change.http://pubs.aic.ca/doi/pdf/10.4141/cjas69-005
PLASTIC BAG EGG STORAGE!!! http://journals.cambridge.org/action/displayAbstract?fromPage=online&aid=618820
Temporary heating before incubation and enclosing eggs in plastic bags during storage improves hatchability, especially when storage is prolonged. A high humidity during storage also improves hatchability, probably due to a reduction in water loss. The changes in albumen pH during storage are discussed in so far as they provide a possible explanation for relationships between environmental conditions during storage and hatching results.
Effects of inverting the position of layers eggs during storage on hatchery performance parameters
Storing eggs with the small end up is an alternative method to improve hatchability and to reduce egg weight and hatchling weight losses in eggs derived from young and old breeders stored up to 14 days.http://www.scielo.br/scielo.php?script=sci_arttext&pid=S1516-635X2012000400003
