Mine are free range totally, dont get locked up or fed at all unless the ground is frozen. We dont have foxes though. We kill as the grass dies as then the meat is sweet off the grass and does not go to fat with false feeding. Best goose with just enough fat and lean meat.Ours are usually hatched by May. You can feed when locking up but they are like ducks , just eat pellets for the sake of it giving you the impression they are starving!
