Rooster comb black in the morning

[cqrmskbans]

My serama rooster's comb has black tips in the morning but they turn red again after I rub them. Is this an indication of an underlying problem? I've heard that a black comb can indicate heart or liver problems. It looks like of like these pictures before rubbing:

Edit for more info: he is 2-3 months old and a bit more than 1 pound. He has a spot of dry fowl pox on his comb right now, a couple other spots have scabbed off already. It's not exclusively in the morning, I think if enough time goes by the tips get black again but I haven't kept track.

How old is he, and is he overweight?

How old is he, and is he overweight?

He is 2-3 months old and just over 1 pound. I don't think he looks overweight but I'm not sure if I'd be able to identify that.

He also has a bit of dry fowl pox right now but not sure if that's related to this is not.

If he doesn't have any other symptoms and seems to be functioning fine then I'd say it's not a huge concern. It is also happen due to lack of circulation so if he's a bit lazy or stays still for a while then it might go black on the tips. Just make sure to check his breathing just in case of a respiratory issue, just to be on the safer side.
