Purple Comb Panic: When Your Rooster Looks Like a Fowl Mood Ring

Oh, a purple comb on a rooster is enough to make anyone's heart do a little fowl flutter, isn't it? First off, good on you for noticing he's still acting like a grumpy little dictator, that's actually a promising sign. A truly sick bird will usually go quiet and lethargic, so his continued attitude suggests he's just *annoyed*, not dying. That said, a purple comb can mean circulation issues or even a heart problem. Since you're in a cold snap, it could simply be his body prioritizing warmth over flashy red wattles, but temps above forty shouldn't cause this alone. I'd isolate him for a day of close observation, just to rule out any fowl play.
