WASHING EGGS~~~~~~~~~~~

Hatching Eggs 101

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!

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



Egg Cleaning Procedures
for the Backyard Flock
SANITIZING EGGS

Most commercial hatcheries sanitize their eggs. There are differences of opinions about how to sanitize eggs, if you feel they need to be. Some experts advocate washing and even lightly scrubbing eggs with soft brushes. Others feel that the most that should be done is dipping for a few seconds. Because of the varying opinions on sanitizing eggs, the following is an opinion of Brower and not necessarily a hard and fast recommendation. Accomplish sanitizing by dipping eggs in solution containing disinfectant that is just strong enough to kill bacteria and viruses. However, the disinfectant should not be so strong as to damage the embryos.

Mix the sanitizing solution according to the manufacturers' instruction. A recommended cleaning solution is Tex-Trol. TexTrol may be available at a local retail outlet. For the name of a retailer search for it online. If using Tex-Trol, mix one half ounce of concentrated disinfectant to one gallon of warm water. You can also use 1 ounce of Clorox to 2 gallons of water. The water should be 100 to 110 degrees Fahrenheit (37° to 44°C). If the egg is warmer than the solution, contamination can be pulled through the pores of the egg before the agent has a chance to neutralize any pathogens.. Submerge the eggs for one to three minutes with dirtier eggs left in solution longer than ones that essentially look clean. Allow the eggs to air dry at room temperature and store as described above--or set in your incubator. A soft paper tissue can be used to dry the eggs but don’t rub the egg with a tissue or any material. Eggs have a natural protective cuticle that helps retard contamination. Rubbing removes the cuticle and can actually drive pathogens through the shell.
