My head hen oreo has been losimg her feathers around her neck and vent. She has not laid for 3 days now, she lays every day. She looks skinny, but it may be the feathers. I switched her back to grower food. I would think molting but her skim is smooth, there are no feather sticks left behind like a normal molt. Could this still be? I'm nervous. No mites or lice, checked her all over and nothing. She still acts normal.
