The very best would be Silver Appleyard or Saxony, but I have known some Pekins that lay a ridiculous amount of eggs and they grow very fast. They are all large meat type birds so they are too heavy to fly. Appleyards are said to lay 220 to 265 eggs a year and Saxony lay 190-240. They are both rare breeds on the LBC's critical list, if you are looking for rare, they are beautiful dual purpose birds and worth the money to purchase them. If you dont want the expense or rarity you might go with Pekins or a medium weigh bird like an Ancona, they dress out around 4 lbs for hens and 6 for boys and mine lay 280+ eggs a year. I think Swedish are about the same size, maybe a little bigger than Ancona, they lay considerably less eggs, around 190 a year.
It depends on what attributes REALLY matter the most to you on which breed you choose. Good luck!
