The Poultry Club of Great Britain:  Egg Production

It takes different times for the egg to pass through the different areas of the oviduct (egg tube), the addition of the shell taking the longest time:

• 15 minutes in the infundibulum (fertilised here if cockerel available plus chalazae added)
• 3 hours in the magnum to add albumen (white of egg)
• 1.5 hours in the isthmus to add shell membrane
• 20 hours in the uterus/shell gland for shell deposition plus pigment
• 1 minute in the vagina which is extruded out past the vent to avoid the faeces

This total of 25 hours to lay an egg explains why hens do not lay every day as the hen will ovulate 30 minutes after laying.......(click on link above to continue reading this article.)

The Egg Law in Tennessee

In TN from  http://attorneygeneral.tn.gov/op/2012/op12-04.pdf
Owner's Use of/and Licensing of the Sale of Eggs
QUESTION 2. Does the Tennessee Department of Agriculture (“TDA”) have the legal authority to impose a licensing fee on those who “sell only eggs produced by their own flocks”?
OPINION 2. No, the TDA does not have the legal authority to impose a licensing fee on those who “sell only eggs produced by their own flocks.” This exemption from licensure should be narrowly construed in consideration of the remedial and public safety purposes of the Tennessee Egg Law. This exemption does not relieve persons selling eggs in the commercial market from compliance with the Egg Law’s regulatory safeguards.
