My Bared Rock Rooster's comb is turning black at the tips. I live in Texas and its August, so no frost bite. Here's the thing... iv been watching him for a while and his comb will be bright red one day and the tips will turn black the next. His comb was a healthy red yesterday, and now today it looks like this...(see photo). Also, he has no other visual symptoms, he is a free range roo, with two hens. He crows good and is very active.
It's probably just because of the heat. Cold and hot temperatures will cause the comb to blacken or turn purple slightly. Another possibility is that he has some heart problems.
Please observe his droppings for any sign of black head. Have you noticed any abnormal behavior. Have a look at the link below http://https://skydrive.live.com/redir?resid=A99F88838D34E678!250&authkey=!AAOQW5GvPFg0J30 Rehan M
