Laying Egg with no shell

[BBB Becky]

We think the same chicken is laying a pure white egg (from brown) and today I found an egg without a shell. They are five month old Golden Comets.
Help...comments. We are new to chickens.

I have a cream legbar - about a year old. It was very slow to start laying but seemed fine then it got a bit lathargic and finally layed an egg with no shell then nothing for weeks yesterday I got another shell - less egg. Maybe she ended her laying run - shortas it was that way and is just starting up again. What do you think?

Really interested in what you found out. I have a CLB that is just starting to lay and her first egg did have a thin shell and was broken right away the next egg was shell less ..
