She told a local newspaper the bird seemed tame and was responding well.
Arun Thong said: "The animal has its life. If it wants to live, we feed it."
However the animal lover confessed she feared its tongue would soon fall out. It was not clear how the chicken came to lose its head but locals say it may have been attacked by another animal.
The chicken is being fed and given antibiotics to help it live.
Arun Thong said she was hoping someone would soon take the chicken off her hands.
She said: "Who will take him and care for him? He will need lifelong care. I have to admit that this chicken is a true warrior with a very tough heart."
The chicken that survived longest without its head is believed to be one named Mike, who lived for 18 months after losing his head in Utah in the US from 1945 to 1947.
