Sorry about the bad quality, I had six eggs but only three were fertile. They all looked like this one. I got them online but I can’t remember were. They were all at 99.5 degrees in a brinsea incubator.
Just saw this. Brinseas are usually pretty reliable but I would still check that the temp and humidity are accurate by calibrating a meat thermometer or one that can be submerged.
If they were shipped that can be a complete toss up.
