The shell was clean. I didn't clean it. Bator was sterilized last season. I've left the other eggs in bator (have to go get ziplock bags) will crack another quitter a send a pic. When I get to civilization!
A fetus (like your post #45 ) starting to break down and not as progressed. The yolk was a nice yellow no off colors of yolk or shell. No odor. Today is day 8 of incubation.
Any pics, duck, 6 day quitter? And what would/could cause it? My sense says bacteria... Maybe. Wasn't the only one that quit on same day. No odor and no discoloration. What would a bacterial quit look like?
