I have hatched out two batches of eggs so far this spring and both have been horrible. The first hatch I did there were 15 eggs and they were under a broody hen and only 5 of them developed, one died before birth. None of the other eggs even started to develop. The second hatch was a batch of 13 eggs in my incubator and only two of the eggs hatched and none of the others developed at all. I have been hatching eggs for years both with a broody and with the incubator and have never had such a problem before and they have always been shipped eggs. Could I be doing something wrong? The humidity and temperature are right where they need to be and I just can't seem to think what would be the problem. Any ideas would be very welcome.
