My hens keep picking at his comb and making it bleed, then they are drawn to the blood and pick him like crazy. I have seperated him 2 times before to heal and then put him back in and the last time it seemed that they were done, he was back to being the rooster and doing his roosterly duties. Well, now they have moved onto his wattles and when I went out this morning, his whole chest was covered in blood, they had pecked his wattles and they were bleeding so bad and then they were picking at his chest where the blood was and some of his chest was bleeding. I brought him in the house and washed him off and have him seperated from the rest of the hens to heal. Why do they do this? and how can I make it stop??
