Llamas can't be healed with hay bales and wheat. They can only be fed hay bales to initiate breeding; it has no effect on their health.
Steps to Reproduce:
- Damage a tamed llama to reduce it's hearts
- Attempt to feed it wheat or hay bales
- Wheat cannot be fed to it
- Hay bales only initiate breeding mode, the llamas health does not increase
Wheat and Hay Bales should heal the llama.
