[Mollans]

Does anyone know why one of my hens produces eggs like this.

Please excuse the blue nails... the Joy's if the blue spray applications lol

How old is bird?

Called corrugated shell, several different possible causes shown here:

Thank you for the link.

I am not too sure which hen it is right now. But it is not the younger birds as it is the wrong colour so that would make her 3 years old.

We have not had any illnesses in the flock for quite some time. I would be surprised if it is too much calcium as her shells are often quite thin... as I found out when I popped them in my jacket pocket to bring them in last week.

Amount of calcium is important,
but so are the other nutrients that allow that calcium to be absorbed and applied to shell.
Have to look at overall diet and environment.

Ok, will do.

She has layers pellets adhoc as well as a handful of mixed corn at night. Veg scraps and lots of egg shells in the garden. Cabbages thrown out for them to pack at. Live mealworms as a little treat sometimes. They free run in the garden.

Wifey ate the egg today and said there was a massive amount of egg white in there with a normal sized yolk
