Comb on rooster not red, very lethargic, Help

[TrishInKS]

My frizzle rooster is down, He normally has a very red comb, about 5 months old. I am very new to owning chickens. Last night it got very cold, but they were all in the coop (same chickens since we got them in Sept, except this Roo as a baby chick from neighbors flock). All of them were totally fine, when it was lights out.
it was 8 degrees outside last night coop temp 30- other hens and roo were all up and about in the am. The coop water froze, but they have heated water outside and at noon when I checked them and put in fresh water INSIDE the coop was when I found him.
All cuddled down in the corner, like a hen on eggs, head down, comb not bright red. I don't feel any think in his crop, but again new to chickens - it is possible I don't know what I am looking for.
Comb is now pinkish gray, he open his eye if I pick him up, doesn't appear injured, make no chirps like normal, moves his legs (have 2 little mini asshole roosters, but they have been "talked to" by this roo.. thought they had their pecking order all figured out. No blood that I can see- he is black feathers
He moves his legs and adjusts his wings, opens eyes when I pick him up. He has been in the house - trying to warm him up for about 6 hours now. Put water near his beak and his favorite meal worms... not touching any of it. Not acting any better.
How do I get him to take water?

Do you have any pictures of him, or can you get some tomorrow? With more than one rooster or cockerel in the flock, he may have been kept from food and water, making him weak. Does his crop feel empty or full? Could he have suffered some frostbite on his comb, wattles, or feet? You can hold a small lid or cup up to his beak and dip his beak into it to get him drinking. A spoon held up to the side may work, or a syringe. Tube feeding fluids can be easy once you learn. A short piece of aquarium air tubing and a syringe work well. Mix some watery chicken feed and a little egg, and offer that before. It is much easier if he will eat and drink on his own.
