Hello all!! For the past week we have noticed 3 of our 4 hens (18 month or a little older Rhode Island Red, golden laced Wyandotte, Minorca, and Easter Egger) have feathers that were thinning out. The fourth (Minorca) has not changed in her appearance at all. I also noticed one hen was eating the eggs after she laid them (Minorca) We immediately started to add oyster shell calcium to the feed instead of just throwing it down in the run and within two days that behavior stopped and has not returned. We have been inspecting each bird for lice or mites daily and see no sign of it. We have always used diatomaceous earth in their dust bath, coop, run, etc. since they were babies. As I mentioned before the Black Minorca mix has not lost any feathers at all. All four are laying still but today, our golden laced Wyandotte laid an oddly shaped egg with a sunshine design and paper thin shell. I’m assuming the feathers and now the change in egg are related to a nutritional deficiency. We feed them purina organic layer pellets. Last week I started giving them more millworms to add protein. No change in poop has been identified at this point. Does anyone have any suggestions or any idea what’s wrong with my girls?
