HELP!! We have been incubating duck eggs. Turns out they've been upside down. We only realized this as all the ducks were externally pipping at the bottom. After realizing they were all upside down we proceeded to flip them the right way (while keeping a high humidity) 4 out of 7 of them are still butting and nibbling at the outside hole. What should we do next? Should we assist them since they were originally upside down??? Need help ASAP!
