My silkie is now 13 weeks. As the chick grew I noticed it had a crooked tail and slower growth than the rest. I really didn't think anything of it. Thought maybe that's the way it feathered out... I'm new to this. Well today it started walking funny and has a crooked neck. It seemed off balance. When I checked his back and his back bone seems to be off to one side which you can see in the picture.He is also starting to twitch his head. I feed them med chick started then switched to grower and electro light/ vitamin water. He is now at the bottom of the pecking order.
