Protect animals in fields please

Have you tried the protect-animals flag?

I did try that in the city protection but it didnt seem to work

Tested this as well.

Added the protect-animals flag to the City Protection field. Placed down a new field. Changed to owner of the field to someone else /ps setowner someoneelse then tried to kill some chickens, could not. Everything works fine.

BTW when you add flags to a field on the config. Those flags will not automatically be added to fields that were placed down previous to the change. Only new fields placed after you added the flag will have the new flag.
