Not an emergency but wondering what this could be. I have buff orphington chickens that are about 9 months old. They were all very healthy and fluffy looking. But Over the last week I have noticed the smaller one getting very pale on her face and comb and losing feathers/ her fluff. She stands out next to my other girls and looks very different than before and it happened suddenly. I thought it was a molting thing but they seem to be young for that and my other girls are not having this issue. Any suggestions on what this is? She is eating and moving around normally so no major concerns besides her sudden change in looks/color. The first pictures is the pale one. Then the last pics are my other girls and how they usually look for comparison.
