To cut, or not to cut?

[fishboyUK]

Ok, I got a question, for experienced breeders . How can you tell that the umbilical cord is tangled (a picture maybe with comparison how a good one looks and how tangled looks), and how can you actually help the baby if you see it's tangled, without hurting it even more?

And I cut my very first eggs this year at day 53 and everything hatched fine .

I don't see how you can tell unless you open the egg right up and start poking at the neonate to make it move.

On the flip side, maybe cutting and excessive disturbance causes the neonate to move unnaturally and tangle itself.

I'm not convinced cutting is in any way necessary.

FWIW I certainly see more cases of neonates dying after eggs have been cut than cases of eggs that never hatched and were cut open to find a dead neonate inside.

I have cut before but only a tiny slit to guide them on an egg thats remains unpipped after all the others have come out.
