Here are pics of 2 ladies whose feathers have changed, and I'm wondering if anyone knows if this is "normal". It's the feathers at the base of the tail, and on the black one also underneath at the top of the legs. I have some whose feathers don't lay flat like they used to, but these 2 have the most dramatic changes. Also, these pics were taken Jan 27 and on the black one the area is now larger. They're both still laying an egg per day and are eating, drinking, and pooping same as the others. These ladies are all 10 months old. Also, is it expected that at this time of year they could all look generally grubby and unkempt? All ideas/suggestions appreciated !
