My Plymouth Rock has a strange neck feather situation and I'm not sure what it is. Her comb is also pale and has shrunk. She has been eating and acting fine. She isn't laying, but that has been going on since November. I am finding quite a few of her feathers around so I'm guessing she is molting, but I want to be sure. It has been really cold around here so I thought was a weird time to be molting. She had some poop caked on her bottom that I cleaned off today to make sure that isn't it. I also have a R.I. Red that is perfectly fine. I attached some pictures and any and all help would be great. Thanks.
