My black copper maran rooster used to have a beautiful comb. However, lately, I've noticed that his comb has turned purple. He is around 8 months old and enjoys a good comb massage. IT FELT COLD when I touched the purple area while the rest of the comb felt hot. I'm concerned and I'm not sure what's causing this.
I've noticed that on my roosters from time to time, too. Wondering what causes it. It never seems to be a problem or affect their health or behavior in any way, just... hmmm
