Define egg
An egg is an oval object that is produced by a female bird and which contains egg yolk which is source of energy for day old chicks in poultry.
An egg is a cell that is produced in the bodies of female in the reproductive tract of animals and humans.
Commercial laying birds normally starting their lay eggs at 126 days (18 weeks).
But it’s depend on birds body weights, weather conditions, day length, nutrition, disease availability, hygiene & bio security.
Thus why sometimes laying eggs at earlier age also like 85-90 days. Sometimes owner might be confused what happened next.
but it’s not worried of fact, it’s naturally occurring for few birds, not getting all at a time.
So take a look eggs colour, size , shape, structure & texture by picture
Egg at 90 days- Near brown but markedly whitish calcium deposit on egg shell.
At 136 days- eggs size are variable due to body weight of pullet. Higher body weight lay higher egg weight & size in laying period
At 126 days- Some birds laying whitish to brown eggs due to uneven distribution of calcium & color
eggs at 122 days- we called also day old egg which is smaller, fully calcium coated covering in egg shell
At 125 days- smaller, near to brown & excess calcium deposition in egg shell
At 127 days- actual color not present & mixed calcium spots in egg shell
