My 8 week old rooster just started tipping over backwards. I have him separated him from the rest of the crew just to be on the safe side. He hasn't been eating or drinking much so I hand fed him today and let him stretch his legs for a little while and this is what I got: He hasn't eaten anything but starter crumbles and I recently gave him a chick vitamin supplement in his water, thinking his drunken behavior might be a vitamin deficiency. Any ideas? I really don't want to lose him.
