New and have a chicken with a beak that looks like its peeling

Beaks are always growing, just like fingernails. So yes, they can look peely. No need to oil it. Peely is normal.

Frost bite will start with just the very tips of the comb turning white. As the frost bite gets worse, the white area may increase and eventually turn black. Paleness of comb is not frost bite. Make sure to have adequate ventilation in your coop. Have them roost low to the floor and venting on either side of your ceiling or eaves, one vent higher than the others. 1 square foot of venting total per bird in the eaves. You do not want to ever completely close off your venting. All the warm moist air from the pooping and the breathing needs to go somewhere and if it has no place to go, it will fall back down as water or frost. So keep those vents open no matter how cold it is!

If they have worms, you might see a lot of diarrhea, lethargy, pale combs, become very thin. The worms eat all the birds food and starve them out. At 18 months of age, they may start molting soon. This will cause the combs to go pale, they can have diarrhea during a molt and look tired.

If you do a lot of free ranging, it never hurts to worm your birds once a year. You can take a poop sample into your vet to see just what you are dealing with. Some people worm on a routine schedule reguardless. Round worms are everywhere and they are quite damaging to poultry. Lots of people worm during a molt since there is an egg withdrawal and generally they are not laying during a molt.
