My flock is a little over 6 months old. They have been doing fine until when I went outside today and all, but one of them is missing feathers on their underside. There is no blood, but lots of bare skin. It has rained all week and I haven't seen very much of them until today. I did see them Thursday though and I didn't notice anything and today when I went out, I noticed almost at once. I did some reading on here and I think they are eating their feathers. I got some mealworms and gave them some of those and I have some sunflower seeds that I am going to start giving them tomorrow. All three of the Australorps are missing feathers. The chicken who is the lowest chick is missing feathers, but not the most. There are two wyandottes and one is missing feathers. I can't tell that the other is missing any. Anyway, does it sound like I am doing the right thing and on the right track?
