Hi everyone I have 14 Indian runner duck eggs in a manual incubator (spread over 10 days) and I'm now on day 31 with no signs of hatching. Having candled them they appear to be alive but none have internally pipped and I'm almost at day 32 now. I have sent the humidity up to around 80 for almost a week now and have been turning them 3 times a day up until 3 days before due date. Could they be having difficulty breaking through the membrane to internally pip? If they are, what can I do? I know that if they pip I can help them out after a while if need be but if they don't even get to that stage I'm not sure what I can do. Any help would be really appreciated - I'm getting really concerned now.
