Deformed eggs!

5yr old bird is infrequently laying eggs like these... Say once a month... Any suggestions besides "hen-a-pause" causing this? Tia!

Thanks for posting that! I'm assuming this would be a calcium deposit? There is nothing about holes in eggs.

Looks like an shell gland malfunction to me.
Not unusual in a 5 year old bird.
Does she lay normal eggs too or only these?

ETA....is the membrane inside intact?

Oh and Welcome to BYC!
