I have 4 roosters; 1 light brahma at 8 months, 1 frizzled bantam cochin a year and a half old, and 2 easter eggers, one just over 7 months and one is around 4 months. All of them except the youngest have developed a blood red color on the insides of their legs. I first noticed it in the cochin a couple months ago. They were so red I thought they were bleeding and that he had been skinned on his legs. Upon closer inspection the skin was intact and not swollen, just a painful looking red color. He didn't seem to mind me touching it, any more than touching any other part of him so I chalked it up to perhaps the girls or another rooster pulling out his leg feathers, as he had a couple missing. I let it be and he seemed fine, still does. Then I noticed it on my brahma last week; again, I thought the girls were pulling his feathers. Today I noticed it on my clean legged EE at 7 months. What is going on? The hens don't have this, just the boys. The youngest hasn't developed it yet but his legs are slate so it might be harder to tell on him. Is this a hormonal thing or is something wrong? Please help! None of them act like it hurts but it sure looks like it would.
