A few days ago one of my 8 week old buffs must have gotten injured somehow. She had a bruise by her eye and a spot of blood on her neck. I seperated her from the rest. She was still eating and drinking fine. Just acting a little withdrawn. Just in case of infection I gave her some antibiotics. Yesterday her head started twitching, that turned her head sideways when she twitched. She was still eating and drinking. However today her head is not twiitching anymore but it is twisted half way around and she seems to be comfortable that way. However it makes it hard for her to eat and drink. What could be happening? Any advice would be greatly appreciated.
