Hi,
personally,I'd decide first if you want large fowl or bantams.A lot of the larger fowl are available in smaller (bantamised)versions.
Pekins are always recomended as an easy,cute bird to start with that can become very tame.My pair were not to start with but have improved.
About a month ago I bought 3 Sablepoot pullets from Sue(Victoria's Poultry) and they have proved to be far better,as well as better layers.
They are curious about people and like to join in whatever you are doing.Recently,at a large poultry show the only hens that approached me in their cages to be fussed were the Sablepoots.They were pleased to see me and chatter to you constantly.
I think though that all breeds of hens have the ability to be tame,some just take longer than others,my pekins are tame,just don't want to handled a lot,my ex-batts are also very tame,but prefer not to be handled a lot.My rhode island red and sablepoots love to sit on my knee and be stroked and fussed.
