Ten or more years ago we raised our own Rhode Island Reds and Plymouth Rock chickens and Guinea fowl and enjoyed the fruit of their labor--all free range and locked them in coop at night if they went in. Guinea fowl eggs are our favorite. Coons, foxes, dogs and then the worst -great horned owls-they got the guineas at night whether the guineas were thirty feet in a big white oak or in a thirty foot scotch pine. The owls were the last straw--we no longer raise chickens. It was a good experience.
