My hens are all hatched last summer. This is my first year with chickens and we are loving it. My girls are laying lots of eggs and seem otherwise healthy except lately I have been noticing weird bald spots. At first I thought it was normal molting ( they have not really molted yet that I can tell) but the bald patches do not seem to go away and not all the chickens have the bald spots. I have 16 hens and no roosters. They do not roam free cuz of loose dogs. We live in Hawaii and the weather is pretty much the same all year. What can this be? Molting? bugs? hen pecking? help!! example of a scraggly bottom... a few chickens have this...bald around the tail. worst of the bald bottoms. It has been this way for several weeks. another bald around tail feathers. and some are totally unaffected..
