If an egg with a shell breaks inside a hen, the shells can perforate the oviduct and the yolk can become a medium to grow bacteria. An antibiotic should be used in this case. This is a serious medical emergency.
To get the egg remnants to come out, give a calcium tablet directly into her beak. It will stimulate contractions to push them out.


Stop flushing the vent, you risk pushing bacteria, fecal matter and egg material back up into the reproductive system.
Feed her normal feed and see that she's drinking well.
Thank you. I have leave in 15min. Gave her 3/4 of a 650mg calcium chew. She has water. Should I feed her at all? Shes roosting in isolation. Scrambled egg or just water?
