First time incubating. Have so far had 3 out of 7 successfully hatch.
But a couple issues
First hatched day 22.5 black/yellow feathered and healthy looking
Second one hatched day 23 yellow feathered early hours in morning still had the umbilical cord attached to shell so was dragging whole shell when it walked. Shell has removed now. Otherwise appears healthy.
Third one hatched day 23 around 3:30 black/yellow feathered but with an egg yolk sack still attached .
Unfortunately the other two pecked at the yolk sack and it looks like a blood bath in incubator.so the 2 were safely removed into brooder and the 3rd is left with remaining unhatched eggs still drying off. Will the chicken survive being its yolk sack has been pecked at ??
Will it fall off eventually being it didn't get absorbed into the body or will it need to be removed to stop any infection??
Any advice would be great.
