Yeah, I just candled three of them, because I was checking on some eggs that just came in the mail that were lightly cracked, so I thought, 'hey, why not?'
It certainly is validating to see those veins!!!
I just candled three of my six goose eggs-- two I wasn't sure of anything, so just put them back, but there was a definite 'spider' in the third! Yay!
This is just day 4 for them
