I bought from TSC last spring. I have several mixes of the red, white and black variety. I had 4 whites, 7 blacks and 15 reds. Suddenly, the hens have decided the black chickens must die. I have lost one, another is bloodied badly (nursing it) and a third is missing all her tail feathers and is going down the road of being severely hen pecked. The rooster (only rooster and black) is also missing feathers. I found a small coop for sale on craigslist and am going to get it today to remove all the blacks. But why would they be doing this? All hens are laying now. I have a 12x12 coop and 2 runs, sizes 20x10 and 10x6. I can understand if it is too crowded, but way only the one color?
