Repairing a Dented African Grey Egg

This was my first attempt at repairing an egg. 
I used white glue and a kids paint brush. Gently applied a coat on the dented area, allowed it to dry for 15-20 minutes before applying the next coat. A total 3 coats were applied. 

I took some pictures of the egg before and after the repair. The third picture shows the egg being candled after repair.
 


There were only two eggs in this clutch. The repaired egg turned out to be fertile while the other was infertile. The egg developed normally but mysteriously disappeared around the hatch date. Although I did not get a chick from this egg the normal development showed that the repair was successful.
