Ok, well I had 2 roosters as the beginning of my flock. One died almost a year ago. One morning his comb turned purple and by the time I found out what it could have been he was dead. Now the 2nd rooster's comb is slowly turning purple. I thought at first maybe he is just cold or its the beginning of frost bite or something but it comes and goes. Some days his comb is back to normal. Yesterday it was normal. This morning it was over half purple. Is there anything I can do for him? Is this the heart again or could it be from the cold? Its not frost bite i am sure but I have no clue what else it could be.
