Hi Ali,
this is possible.
This could have many different reasons, the most common being too high temperature for your species or a nest which is too dry.
Are you sure they are eggs? They might be larvae and if your colony is in hibernation or a diapause, depending on the species, the larvae tend to shrink as they lose water and can become a little yellowish. This is a natural process and as soon as the colony comes out of hibernation, the larvae quickly grow back to their normal size and start developing again.
Which species are you keeping and how big is the colony? Which nest do they live in and what is the temperature?
