Helped my neighbors save some Saxony eggs after a bad egg exploded in the nest and momma duck then abandoned the nest. They then sat in the nest for the last 30ish hours without momma. Out of 14 eggs, there's 5 now in my bator. 3 definites, 1 maybe and 1 long shot. One of the definites (good embryonic movement) has exploded yolk all over it and the other four are pretty "icky" too. So, how do I clean these eggs that are already in a sensitive state. Approximately 10-12 day development. Bacteria invades quickly.... Any ideas? Destroying them is not an option.
