I don't recall ever seeing blood on my hens, and I've had hens for two years now. My rooster is 27 weeks old this Tuesday, and in the last month or so he's hurt a toenail, which bled a bit, had a bit of blood on his tailfeathers, and today he has blood on his hackles. It looks like a scab on his comb bled onto them. He is the only rooster, so he's not getting in fights with other roosters, and I don't see the hens pecking at him or anything. Could it be that roosters are just more active or something, causing them to get injured more often? I have no idea how he got the scab on his comb. I don't think I have anything to put on it. What should I buy to treat it with? I wish I hadn't given my Rooster Booster away.
