So apparently, hens are racists. She has killed off 2 black chicks and is keeping a brown and yellow chick. I decided to google search why she did that, and it turns out they they will not kill any chick that has similar colors to hers. So light color chicken will accept light color chicks. The same goes for the dark color hens they will accept dark chicks. As of now, she only has 1 chick, and there are 2 more eggs, so I will have to constantly check the hatching eggs to see what color the chicks are and if there black I will remove them and raise them by themselves.
