SUPER Porous shells? Anyone??

[Rare Feathers Farm]

I know.

I'll just probably put them back to the WII after I candle & then I'll buy myself "fresh" batteries.

So did anyone come up with a reason why they look like this?

I found this info here - http://edis.ifas.ufl.edu/PS020#TABLE_2

B. Thin, porous or shell-less


Inheritance influences porosity and ability to produce strong shells

Lack of sufficient calcium, phosphorus, manganese or vitamin D3

Vitamin D2 mistakenly substituted for D3

Excess phosphorus consumption, especially by older hens

Ingestion of sulfanilamide (sulfa drugs)

Disease: Newcastle disease, infectious bronchitis, avian influenza, Egg Drop Syndrome 76

Hens exposed to temperature over 85-90°F

Age of hens: incidence higher with older hens

Premature laying of the egg


----------so it looks like it could be many different reasons
