It sounds like you are doing well. I've helped mine too many times (so no judgement from me!!)...the biggest issue I think I;ve had is trying to ctually get them out of the egg too fast. Now, I try to not take away so much shell that they can "fall out," and if I peel the membrane back (inside membrane with veins) I do it once there's no red veins seen when I moisten it, then leave chicky inside until it starts twisting it's own way out. Anytime I've help it upside down to encourage it to actually emerge there's leftover yolk. So, I try to let it rest even if half way out of the egg till it comes out on it's own.
