Discolored comb on Serama rooster

[MichelleKing]

This morning Rio’s comb looked discolored (slightly purple) at the back end, and felt slightly cold to the touch.

Background
-1 year old
-Hatched him myself
-Indoor pet, lives in a giant townhouse with his girlfriend (another Serama)
-Never been exposed to another flock NOR any other birds NOR any other pets
-No feather loss no visible mites
-Crowing vigorously as normal
-Running around like normal

Diet
-organic crumbles 22%
-chia seeds
-mealworms
-sesame seeds

What I’ve done
-nutridrench
-rooster booster poultry cell
-probiotics

Other than that I don’t know what to do.
He is my BABY. Please help if you can. I’m praying he’s not having heart issues

This happens to my Phoenix rooster unusually when the weather changes and he gets a runny nose and I was told it is just lack of oxygen
This has been going on for 3 years now and it doeant affects him in any way I just keep them in a large indoor enclosure where I can control the temp and as far as I'm aware none of his off spring have this
(My rooster is 6 years old)

Thank you that is reassuring.
