I bought a pair of Gold Brabanters last year around September, and the female just started laying eggs a few months ago. I've kept some in the incubator before, but after a day of breaking a small hole in the egg, they all die, like they gave up. That happened with 4 of them. Then this past week I had two hatch that I kept in a box with water and food and a heat lamp that I use to raise other chicks that works every time. Those chicks died in the middle of the night. I don't know why. If anyone has any advice or know why its happening your response will be much appreciated.
