Can eggs break in a chicken?

Yes, eggs can break inside a hen, and that can actually be quite dangerous. yolk peritonitis is a serious condition that can occur when egg mass becomes trapped in the hen’s body and causes a bacterial infection. Hens suffering from this condition usually slow egg production or stop altogether. They may also be less active, have trouble breathing, and have a bloated stomach. It’s usually treated with analgesics, anti-inflammatories, and antibiotics, although surgery is sometimes needed.
