Chicken has increasingly white comb. Should I be worried?

[jentav]

Hi Everyone,

Here is my just over 2 year old (I think) Buff Orpington. Her comb has become increasingly white and since it has gotten cold her egg production is zero. She recently loss a ton of feathers and is still dropping a few here and there. Any ideas as to what might be causing this?

Thanks in advance!

I will also post a picture of her coop mate a Rhode Island that has curious issues as well.

I believe she is moulting, my hens never seem to moult but this is what I have heard other members mentioning. No need to worry
