I wonder if there are any idea about what might have happened to my last batch of eggs. I use a Hovabator Incubator with an egg turner and a Little Giant for pipping. Both have been working wonderfully, and my hatch rate has been about 80-90%. I ordered 24 Buff Cochin eggs from a seller on Eggbid. They were advertised as being from award winning exhibition lines. I was given the NPIP ID, and the seller indicated that eggs were shipped day of hatch, not stored. When I got the eggs they were packed in bubble wrap with no foam. Normally my shipped eggs have bubble wrap and foam. Next issue I noticed was that BC was written on each egg in marker. I always label my eggs in pencil and have always heard that marker can be damaging to eggs as it bleeds through. The hatch date for these 24 eggs was supposed to be July 6th, and the incubation went perfectly. No temperature problems from power outages-no egg turner malfunctions, great humidity, etc....As of yesterday we had no hatches and decided to crack open a couple eggs to see if there was any development. The first three were just rotten egg...no chick development at all, so we decided just to check all of them and move on. Out of 24 eggs, 3 had partly developed chicks, and the rest had no development at all. Was this just a bad seller? Was it the marker labelling they put on them? Is there any special treatment I should know of for eggs received in the mail? Are Cochins difficult to hatch? Our bantams at home are Old English, and as I mentioned our hatch rate has been 80-90%.
