If they are round and plump. Infertile eggs also tend to be yellow. Even if the eggs are dented I would still put them in an incubator until they mold since they can still be fertile and produce perfectly healthy babies.

Can cockatiels sit on bluebird eggs and raise them?
Well, it depends on if the cockatiel is willing to raise the egg that is obviously not it's egg. If it is, then the bluebird chick will learn how to live life as a cockatiel. The bluebird will never have a crest, but it will learn the cockatiel's language as it's own and think it is a cockatiel because that is the type of bird it is living with. However, if you had a wild cockatiel and you set a bluebird egg in with the other eggs, the cockatiel would reject the eggs because they do not look right or smell right, and would drop the egg out of the nest. I hope that answered your question. :) - Emily Sage
