Yes, I've tried straightening him, but he just winds up in that position again.
I wormed him with SafeGuard or something of that sort. It was goat wormer and it will get roundworms, tapeworms, cecal worms and I believe something else.
Woodland Woman, good try but if it were botulism, he would have been laying on the ground paralyzed. Limber neck comes from a person picking up the bird and the neck being so limber that it looks like the bird is dead. Feathers will come out of the bird affected with botulism very easily.
Internals are a thought, but his poo comes out completely normal? Not even liquidy??
