Weird color egg.

[aart]

'Speckled' eggs can happen for several different reasons...very few of which are a 'problem'.
Can be caused by:
Excess or uneven pigment coating.
Excess or uneven cuticle or bloom.
Excess calcium deposits.
Porous eggs can appear speckled.
Some birds lay them consistently, some only once in awhile.
The pigment or bloom can change appearance when wet, then change back when dry again.

As long as bird is getting a good diet and is healthy in every other way, it is no cause for concern.

The egg is fine when the shell is rough and bumpy the den just ate a lot of calcium. At least more than useual wich leaves extra spects of calcium.

Not enough calcium would have resulted in a sort of rubbery shell.

I agree. My buff orp ALWAYS laid an egg that looked like that, and the black jersey giant laid many eggs like that too. I had a golden comet go through some kind of reproductive trauma and quit laying for 3 weeks. During that time I started the process of switching the entire flock to a flock raiser feed (lower calcium) from layer feed since the gc wasn't laying, and noticed the eggs of the others look MUCH better and don't have the excess calcium spots nearly as much. The gc ended up laying again but I have kept the flock on a mix of 50% layer feed and 50% flock raiser with oyster shell available (which they NEVER eat) and the eggshells from all my girls have now been perfect!
