Small hard bumps at top end of egg shell

[Carol Harvey]

We have had 3 Warrens for a year now and they are indeed excellent layers. However, for the last 2 or 3 months, one of them is laying eggs with small hard lumps at one end of the shell and we do not understand why. She seems well otherwise. The eggs inside seem ok but I am reluctant to give them to my family just in case. Any suggestions or information gratefully received. Thanks. Carol Harvey

They are probably calcium deposits. Not at all uncommon and with some hens these deposits come and go.

Welcome to BYC!

Pictures would help, but it sounds like calcium deposits, which are normal and can happen.

Those are calcium deposits, as others have said. It does lower the shell durability a bit and it looks ugly but they won’t affect the interior quality of the egg, so they are safe to consume.
They are probably coming due to the age of the layers.

Thank you - very helpful - and reassuring!

Many thanks for that. I have one other concern which I would be v grateful for a comment. One of my three chickens (and I’m not sure which one, although I have checked!) is producing very tarry stools. Again, all three seem to be well and healthy, but this has been happening for several months now. Your comments would be really appreciated.
