I did a post mortem on 3 UNPIPPED eggs that were on Day 23 of incubation.
A VERY FASCINATING SIGHT I BEHELD:
The chicks' posterior was at the large end of the egg, with the heads at the small end. Like a "BREECH" baby!
Has anyone ever seen this before? What's the cause? Incubator operator error? OR genetic defect? Could my incubator have been at fault, since the large ends of the eggs were never raised too much higher than the small end? In other words the eggs laid on their sides at all times. It appears as though the chicks drowned when it was time to hatch because they had no air sac at that end to puncture.
These were Cuckoo Marans, and I can attest that Cuckoos are easier to hatch than the Black Coppers! But these little chicks were fully formed and had absorbed most of the yolk into their tummies. It appeared these chicks were at the exact age normal for pipping.
When does a chick go into position for hatching? Obviously before the pip but when?
Hope someone can answer this. Thanks in advance.
