One of my Black Stars has a bald belly. No visible bugs or injury & I had noticed a lot of black feathers around the nestboxes in the past week, but thought she was molting. None of the others are showing any major loss of feathers like this. Could she be thinking of going broody??? There are no roosters on 2 Dogs Farm but I do have wooden eggs in the boxes. If she is broody will she set on those?
