I’m skeptical that x-rays have any effect on hatching eggs. Old wives tale? Guess I should research since I ship lots of eggs, but I’ve not seen anything definitive. If anyone has any good sources they’d like to share, I’d be interested.
It does damage growing embryos. This study was actually focused on whether a higher number of females would hatch when exposed to short periods of radiation from x-rays but if you read through it talks about the high mortality rate from being exposed to x-rays as well as the lesions and other permanent damage that can occur in surviving chicks.
