Its not shrink wrapped. It doesn't look quite ready yet. Sorry you lost so many. Incubating has a big learning curve. Its ok. What all did you do at lockdown? Maybe we can figure out what happened. I'd rub some coconut oil on that baby's membrane to keep it moist and check on him again in a few hours. Look for them to make yawning/chewing motions. That means there's still yolk.
I moistened the membrane with paper towel and stuck him back in. Is that okay? He is still yawning/chewing. One of the other babies still drying pecked at him and he bled a very tiny bit so I hope he will be okay. That was while ago and the duckling in the shell is still doing okay.
So on the evening of day 24 I noticed one duckling has externally pipped. So instead of waiting till morning I put them all into lockdown that evening. I candled them all one more time and then put them on the bottom of the incubator with the lowest dip in the air cell facing up.
I kept the temp the same as it was all through incubation. It fluctuated between 99-102 throughout the first 24 days. occasionally near the end the temp would spike to 106 but I was always around and brought it back down. All 20 eggs were alive when I locked down.
For humidity I raised it initially to 65-70%. after a day someone in my area (not on this forum) told me that 75-80% was better. So I brought it up to that and it stayed in that range.
I should also mention (incase this plays a factor) between day 7 and day 14 I had the humidity running at 30-45%. On day 14 When I candled again I noticed the air sacks were not where they should be - they were too small. So I brought it down to run between 20-30% and that seemed to work to enlarge the air sacks.
I did open the incubator during lockdown. Maybe that was my mistake. I must have opened it about 7 times. I was quick and did monitor the humidity and it didn’t get below 65%.
but everyone who has externally pipped has hatched so far.
the ones not hatching internally pipped but never externally. And some look like they never internally pipped.
Any advice would be great. I will be doing this again and I’m all about learning.
