Light colored comb?

[cabela]

One of my hens has a really lighter colored comb than the rest of my girls and she is losing alot of feathers? I am a first time chicken owner, only a year, so I am not sure what this could be. Any ideas would be greatly appreciated, Thanks

Post a picture for more accurate answer. But if the comb is getting really light then it could be a sign of sickness.

I will try to get a pic on tomorrow, it is too dark outside right now. I thought maybe she is molting?
