I noticed last week that my roo was holding his head sideways....you know ...like when they see a hawk or something flying over??? I though nothing of it until this weekend, and I saw him eat or drink, and his head would spin around over his back and stay that way. Several times over the past 2 days, I thought he was dead, only to go poke him and he raises up with that crooked head!!!! What could this be?? I'm so scared that it may be contagious to my other birds. It seems neurological to me......anyone???
