Chickens have slight white tips on their combs

[Bigbluefrog]

my pullets have little white tips to their combs.
Is this normal? They look healthy.
I didn’t heathe coop except if it was below 0 with windchills.

they like to sleep in the enclosed run and it gets down to 20 F at night
Our temperatures are all over the map.
No more wind protection- I took off the plastic in mid March.

It is just a slight white tip.

Hard to tell, could be a slight touch of frostbite.
Personally, I would leave it alone.
