You guys are talking about specific incidents with a couple quail. Ive kept notes over many thousands of birds. Assisted hatching may sometimes lead to a thrifty bird but most often it wont. Keep track of when they start to lay, egg size, hatchability of their offspring, etc and then you'll see that most of those birds arent of a similar quality as healthy birds. If youre doing this for pets i guess it doesnt matter but if youre concerned about genetics and thrift of the bird assisted hatching is a no no.
Also adding a little water to the bator wont save a pipped egg from shrink wrapping. If it was that simple you could just open the door whenever you want during lockdown.
