Chicken laid wad of tissue with a shell-less egg

[danlan]

Question for you: one of my chickens laid this strange wad of tissue along with a shell-less egg. Pretty sure it's my Jersey Giant. She is 2 years old and they all have free access to oyster shells, as well as crushed egg shells.

She hasn't laid an egg in about a week, but I attributed it to perhaps being ready to molt, as my other chickens are molting as well. Normally she lays 5-7 eggs a week, although egg production has been low recently due to summer heat.

Is this weird tissue thing something to worry about?

It looks like it might be a lash egg, and yes, that is something to worry about.
Here's a couple of other threads on it https://www.backyardchickens.com/threads/lash-egg.1544137/#post-26064312

If you still have it, cut it open and see what's inside. If there's more layers of the same material inside it's a lash egg.

It can possibly be treated with antibiotics but as the cause of infection can vary, antibiotics will only work on a bacterial infection.
