Hey, I’m just gonna jump in here I just wrapped up incubating 3 different sets of shipped eggs plus some from home in my 2 incuviews. It was a dismal hatch this go round sadly but the eggs that shipped from the shortest distance and my own eggs had the best outcome- I knew I was really risking it with how far the other eggs were coming from. But I had 2 other hatches in the incuview earlier this year and had over 90% hatch rate, so I think it’s more a shipped egg problem then an incubator problem. But my incuview has always ran way too hot unless I calibrate it to between +1.2-2.0. And I have temp differences from 99.5 along the front to +101 in one back corner and 100.5 in the other. So I just do my best to move the eggs around so the same ones aren’t always in the hot spots. And with shipped eggs I cut the bottom out of the cardboard egg cartons and cut the sides way down and put my shipped eggs in that until the aircells stabilize.
Yes I definitely agree about it being a shipped egg issue. In spite of each seller packaging the eggs well, they just don't tolerate shipping well. I'm in central NC and have received eggs from Texas, Florida, MO, Louisiana, and Ohio. The end result is horrible for probable good eggs that would have otherwise developed and hatched. I have been incubating in my Nuture Right 360 with a cardboard egg carton cut into individual cells, with the bottoms removed (like little bottomless cups with dipped sides). I have the same in the Incuview. I have left them to incubate like this for the entire time. I lost all of those eggs but they were a bit past prime incubation time when I received them (up to 16 days since being laid) plus went through USPS and spent Memorial Day somewhere in route. I just hope the egg carton and hand turning (leaning side to side for turning) wasn't the demise, but apparently those eggs had an awful lot of odds against them. Plus I've heard seramas aren't easy to hatch and they were seramas and serama mixes (crosses?). I am excited about incubating in the Incuview with this shipment. I've been diligent about checking everything and it's proved itself after running steadily for days.
