Egg with extra shell material

[craddockchicken]

My Buff Orpington hens eggs have looked like this for the past 2 weeks or so, what is it? If you rub the egg most of it falls off, is this somthing that needs attention or can be dismissed

Looks like it may be a calcium deposit.or she's been pooping on her eggs. I know this is gonna sound really weird, but what does it smell like?

It doesn't have no smell, when you rub the deposits they flake, chip, or break off for lack of a better word.

It is probably just cloacal liquid mixed with poop or undigested food. if she has any other problems, please let me know. Thanks.- Goofy
