I have never externally pipped an egg that had no internal pip. I don't know.. I would be afraid of shrink wrapping.. better watch that egg very close.
I stopped turning at day 25. I also just barely opened the incubator and stuck my candler in to peek at the eggs so I knew when they internally pipped. I misted the eggs with water when doing that so they had plenty of humidity.
Give him another day and if he still can't get his feet under him you may need to tape his legs. Search splay or spraddle legs, I have done it a couple times it works wonders!
Thank you so much!! I just hatched 4/6! I wouldn't have been able to have these babies without this information. All my babies were mal positioned but with a little help they are out and drying!!
