Hi all, We're incubating our first ever hatch of six White Campbell duck eggs. The eggs were posted and all 6 developed into embryos. From what we've learned so far today should have been lock down day but we're concerned that the air cells are smaller than they should be. We're aware that this could be a humidity issue and have lowered the humidity to the ambient of 34% for the last few days with no effect. We've stopped turning today so the ducklings can get into hatching position but we're hesitant about raising the humidity just yet as when we candle last night there were no signs of internal pipping. All the embryos were moving though. Should we up the humidity now or wait for signs of internal pipping? We're very worried about them drowning in the shells. Also we're worried about candling them now in case we disturb them so how would we know when to go into lock down? Advice would be greatly appreciated!
