It's normal for the neck to be swollen. That's how they get spring action to zip out. The belly is also usually soft and swollen from absorbing yolk. Looks like it suffocated. I've had that happen in the incubator.Baby's head and neck look and feel really swollen, squishy and soft... Her stomach looks normal but also feels incredibly squishy. The yolk was close to fully absorbed as was the blood.View attachment 2113556View attachment 2113557View attachment 2113558
