I have one hen out of eight whose down feathers e showing through her new feathers (pics below). Is this ok? Is there something I need to do to fix it or should I just leave it? They aren't show hens, just layers and eventually food so I'm not worried about how they look so much I just want them healthy. They are 6 weeks old. Also, the hand on the neck is my three year old petting her, not someone choking her as it sort of looks like from here, LOL!
