i certainly would'nt put them in the freezer, as a youngster we kept poultry, and used to keep eggs for weeks, before puting them under broody hens, we also used to put eggs u got from the local shop, (not many as u only got one per person per week) under them and they hatched, as far as keeping eggs for a year i dont think they would keep fresh that long, but weeks yes, but not in the freezer, i think they would crack,
