:My old female did this too. She discarded maybe 3 bad eggs. I e-mailed a friend who was more experienced with breeding burms and he said usually that means females are going to lay a bunch of infertiles. Sure enough about a week later my female laid 73 eggs and all but 3 were infertile. Those three eggs that looked good could have be infertile as well. They died about 2-3 weeks during incubation, but it could have been my fault. Anyway, good luck and let us all know what happens.
Well she laid another bad egg. That is 2 nights in a row. Well looks like you were right. I hope my other female gives me some good ones.
