I could really use some help. I have 2-Buff Orps and 1-Wellsummer. They are about a year and a half old. The Welsummer started to molt about a week ago and now looking really small and has areas on the back and underside that are down to the skin. She is just pathetic. Starting yesterday, I noticed a few feathers from one or both of the Orps. Today there are a lot more. It seems like the wrong time of year and it is cold here now. Also, the amount of molt seems extreme. I did spread some diatomaceous earth in the coop, nest boxes and areas where they spend time. Maybe I should be more generous with that. I have also added probiotics to the water. They free range in my large yard. Also, they have taken a dislike to the crumble. That was a few months ago. Now they are losing interest in almost everything, especially the Wellsummer. However, there does seem to be a sign of re-growth on the back. I am worried because she is so lethargic and shows so little interest in eating.
