I am a relatively new chicken owner. I have a 6 week old NN turken with a strange growth or scale on the back of her neck. I was hoping someone might be able to tell me what it is and if it's contagious.
Welcome to BYC. It looks more like a growth to me, but if she has been scratching there or being pecked I suppose it could be irritated. Was she vaccinated for Mareks disease? Mareks and lympoid leukosis are 2 diseases that can cause tumors. I would put some iodine or plain Neosporin ointment on it for now, and look for any lice or mites on her body.
