Eggs without hard shell?

[es425cuete]

Today i found an egg without a hard shell, it was like a turtle egg or reptile eggs.
Why did it come out like that?

Thanks in advance

Occasionally a hen will lay a shell less egg. She may have gotten stressed during the stage of "putting on the shell" and rushed the egg thru. She may have been lacking some calcium that day, or for some reason the shell gland did not do it's job.

Unless it becomes chronic, it is no big deal. You will see this occasionally in your flock.

Make sure to always offer up crushed oyster shell on the side for the layers so nobody becomes egg bound.

A related question, so I didn't want to start a whole new thread, what other items are good calcium sources?
My boyfriend is severely allergic to shellfish so I'd rather not keep a bag of what amounts to poison in the house or have him have to risk dealing with it to care for the quail if I have to be away for work or something.
I know kale blocks calcium absorption but still provides more than it blocks, I just worry about it as a dedicated source of calcium supplement. I'd also prefer something more shelf stable.
We normally purchase duck eggs for eating at a local farmers market (our quail haven't begun to lay just yet), would washed and baked crushed eggshell be a suitable alternative? Once we start getting them we would naturally be giving quail eggshell instead.
Any other options I haven't thought of that would be even better?
Or any issues with sterilized eggshells I'm unaware of?
Thanks,
Jessie

Yes, crushed egg shells are a viable alternative.
