Looks like a lash egg. The cause is salpingitis. It is an infection and sadly often fatal.
How are your birds acting? Anyone puffed up or acting a bit off?
I had a hen that lived another 2 years after a lash egg so often but not always fatal.
Do you still have it? If so can you cut it open and post a couple pics?
I could be wrong....
Antibiotics may or may not help. Some say if it is treated early, they can help, but some say when lash material is seen, it might be advanced. It is worth a try. Unfortunately, Baytril (enrofloxacin) which is banned for chickens and has a long egg withdrawal time, is the best one to use. If that is okay with you, you can sometimes find it here or from a vet:

Dosage is 0.05 ml per pound of weight, or 0.25 ml for a 5 pound hen twice a day for 5 days. Wait a month before eating any future eggs.
I hope she continues to do well.
