So out of 100 eggs, I hatched 32 (first hatch, don't open the bator unless necessary!) one died a few days later... I have three goldens in the group, and today I noticed they all had a bald spot!! I thought they were getting picked on, but when I looked closely, it was darker feathers coming in on the top of their heads! Is this normal? Or will the rest of the bird darken too?
