The candling apparatus at an 'egg factory' far, far out preforms anything we can do at home.@aart That's what I've been doing with the eggs I share so far. And was also thinking of offering to replace any if they show up once I am able to sell. I tried candling and couldn't see anything.
So in your experience, are the calcium deposits an issue with the hen not breaking down the oyster shell enough? Relative to the size of the shell in any way? Or an indicator of something else? Just random? Or anything to be concerned for. I know I've seen them a lot, just never really considered it.
Tho I have seen a blood spot in a light colored egg while checking eggs I set to incubate once.
I set it anyway, it never developed, and I confirmed the blood spot inside when doing eggtopsies.
I believe that the calcium deposits on an egg shell has to do with the way the shell gland(uterus) functions.
The oyster shell fed to the chickens does not go directly onto the egg shell,
it goes thru a many stepped process thru multiple organs to get the calcium from the oyster shell in the gizzard to the egg.
Some birds have them once in a while, some never have them, I have one bird now that always has them.
