My 3 welsh harlequin duck eggs are on day 31. My temperature was to low till day 18. It was at 99.5 and was advised to raise it to 102 for still air. My humidity was at 55% till day 23 when I realized the air fell was to small. So I ran dry till day 28. The air cell were caught up, put water in an ran ar 65%. The cells dipped down and internally piped on day 29. Day 30 I placed a safty hole because no external pip. Now day 31 I peeled the safty hole of one back to reveal the membrane. Following these instructions https://www.backyardchickens.com/articles/guide-to-assisted-hatching-for-all-poultry.72886/ The veins are still full of blood and the duckling looks huge. Are they to swollen from the high humidity early on to progress any more. I'm at a loss as to what to do. I nicked the membrane with a piece of shell and it bleed a drop of blood then stopped and clotted. It's still making the yawning chewing. I assume trying to absorb the yolk. Will it just take a long time to absorb then have space to maneuver out? Should I check the other eggs..
