I have been trying to hatch out some of my eggs. My rooster is a Black Copper Maran and the hens I have are golden comets and black orp/marans crosses. 2 of my Orp cross hens had 10 eggs under them that they were sharing. I had 5 little black chicks hatch (which I am assuming came from the black orp/maran momma's) and 5 eggs that had little yellow babies with black spots on them (I am assuming are the golden comet chicks). 4 of the yellow ones died before they hatched and 1 hatched and died a few hours later. I have another black orp/maran hen that has been sitting on eggs I ended up with only 2 of them under her, and one started to hatch this morning and died before it fully zipped and it was a darling fully formed little yellow chick again. She has one more egg under her that wasn't doing anything when I checked this morning so we will see what happens with that one, I am not sure what color it is going to be. Why are the yellow ones dying and only the black ones making it? It is so sad and frustrating!!!!
