It's also my BR too. I noticed they have loss some weight. They are the oldest so fluffier butt than the others. They have free calcium and grit to eat. Also free range too.Does she have an over fluffy butt? I have a few of my big girls that tend to have this problem. The droppings build up because they have so much fluff. I trim their feathers and it goes away. It's on my list to do now that it is spring. I need to make room in my schedule for a spa day for the chickens!
What wormer did you use? If you used Wazine you might want to try Safeguard or Valbazen since Wazine only gets roundworms. You could also take a poop sample to a vet and have it checked for worms and bacteria. (fecal float and gram stain).
