I have a hatch in progress and I have 4 healthy hatchlings (out of 8). This one has been pipped (see picture) since 8 o'clock this morning. He may have pipped during the night, but I know it has been at least 12 hours and there has been no progress. The membrane is so paper white and looks so dry. I have been keeping the humidity at around 70%, but am worried that he is stuck. I cannot see any movement within...such as a beak pecking...or no rocking. I do however hear him peeping from time to time. Today is day 21 for him. I feel confident in my ability to help him if needed. Can anyone please advise me if I should intervene? I am so afraid that I will go to bed, and wake up to him being in the same condition, and no more peeping from him. I would feel horrible. Please advise asap. And thanks so much.
