Well...here's what I have learned...I have hatched several hundred eggs, so lots of practice. I do step in and help IF need be. I have had chicks physically dry out and get stuck. Does that make them weaker??? Absolutely not. This often happens with the late hatchers.
The incubators been open quickly to remove the other chicks that have hatched and dried out, reducing the humidity for the existing chicks hatching--this is by no means their fault. When helping, I only step in if a chick has pipped and not hatched in 24 hours. I then assist. I peel away a little at a time. If you see bright red blood, stop. I try again about an hour later. I have had more success cases than not and my chicks come out fine and grow up strong and healthy. Just my 2 cents...
EXACTLY what I did... out of 19 eggs, I had 10 hatch (one I did help b/c the membrane had gotten VERY dry; probably from my having opened the bator to take the others out after they were dry), 2 totally clear, 3 with early signs of life but then quit, 2 just funky rotten, and 3 perfect little beauties that died
b/c I didn't know that it wasn't ok to take out the little ones once they dried. I took them out b/c my incubator is a Lyon Turn-X (round in shape) and there is NOT much room in there, especially after the babies hatch and start trying to move around. They're walking all over each other, the broken shells, walking on pipped & rocking eggs, etc. I left the unhatched ones in the 'bator for 5 more days. One of the unhatched ones that died was rocking. I looked at the humidity and it was pretty low (approx. 31%) so I raised the cover and misted them with warm water but the egg stopped rocking and there was no more movement. Did I finish it off???
