I have about 100 White Rock chicks that are two weeks old and about 20 of them have bloody "tail areas" from being pecked on. I've now moved the bloody ones to a seperate area, but when they were being pecked at they had been combined with a combination of Buffs, Rhode Island reds, and black chicks. Could it be that they had been combined with these other breed of chicks b/c none of the other breeds have bloody tails on them. And yes, I give them unlimited amount of food and water.
