1) I don't think that'll happen often with the father. Otherwise hardly any Jubjubs will ever be born, especially since a Jubjub cannot stand being away from her husband. Remember that the Humpty is a mutant species, meaning their birth isn't guaranteed even in the right circumstances. Evidenced by this line: "Jubjubs are born from the eggs, but there is a higher probability that they will become “humpty eggs” than eggs laid by Jubjubs." Note the keywords, higher probability. Meaning it's more likely that they'll mutate than Jubjub eggs, and that it's not guaranteed to happen.

2) I don't think the egg a Humpty is born from is the same egg that they form with their white slime. They're probably born from regular, but still big, eggs and when they hatch, they expand their slime to form a massive egg-like shell to trap their mate in.
