I am on day 22 with my last surviving sebbie egg the air cell had not grown as much as I would have liked from dsy 18 but it has had a 4% weight loss during those days, my question is when do I move to stll air Hatcher and raise humidity? Do I wait until external pip? MI
Wait for internal pip. When you candle, you'll clearly seeing a beak shadow withen. It takes the sebbies until about day 30 to pip internally. To be honest, with my last goose hatch, I waited until external pip.
