Hi, I always thought Betty was just dirty from where the boys mount her and the mud had stained her pretty white feathers. But someone recently mentioned wet feather, I didnt even know it was a thing and now I'm unsure whether betty is just dirty or if she needs any special care? The bottom picture is a good few weeks ago and the top one is her all muddy today. They have access to a paddling pool and I've not bathed them indoors since they were tiny so I dont want to stress her out for no reason if it's not needed. Thanks
