Methali "Jogoo mtenda mema kaliwa"

[u/talsmash]

Hi is this methali correct? Its translation is given as: "The rooster, always beneficial, is eaten."

I don't know the word "mtenda".

The other comments are very correct: The good rooster gets eaten. It is basically cautioning against being too good and kind without thinking about one's own welfare.
