I have a 11 week old Silkie "Andy". The past few days I have noticed his neck tilting to one side. He still eats and drinks well. My other chicks are not picking on him. At first, I actually thought maybe it was his vision but after researching the post here - I am confused! I have read about the common vitamin deficiency in silkies. Right now, all chicks are still being feed the Purina chick Starter (medicated) and of course treats (yogurt, boiled eggs, cheerios, fruits/veggies and etc. What type of vitamins do you give and how much? Do you also supplement with the Vitamin E? How do you give chicks vitamins? I am a new and very proud chicken owner....so I need details. The more post I try to research - the more confused I am! Please help, I don't want him to get any worse!
