White spots on BO eggshell

[aart]

Actually I'm pretty sure it's a spotty concentration of the thin protective film they in case the eggshell in to shield it from bacteria, I have a couple of hens who do it to. For some reason it seems to be pretty common in orpingtons

'Speckled' eggs can happen for several different reasons...very few, if any, of which are a 'problem'.
Can be caused by:
Excess or uneven pigment coating.
Excess or uneven cuticle(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.

This is so helpful I've noticed we frequently seem to have a layer with white speckles and noticed its mostly noticed from our friendly BO Rosemary. I've caught her laying the speckled eggs a few times but we have them quite often so I wasn't sure why but if its nothing to be concerned about since shes healthy its a relief.
