We have a friendly cross breed dog (Great Pyrenees x Mastiff) free to a good home with out chickens. This dog cannot be trusted around poultry unfortunately. Otherwise would make a good family or watch dog.
Hi, I used to be in collie rescue and so learned a few things about "free to a good home". People who have illegal dog fighting rings will look for free dogs to put in the ring so the young fighting dogs can kill them and build up their confidence. If it is a good home for your dog they won't mind paying for him and they will be able to afford to feed him, hopefully. If you value your dog it is safest to put a reasonable price on him.
