My kids would say our Polish girls. They have the funniest personalities. Personally I'm smitten with Speckled Sussex, even though I don't own any. Yet.
I can't believe I'm going to say this, but my Silver Spangled Hamburg.
Took me a long time to get used to this weird little chicken! They are like cats - independent and defiant. She does lay her little egg every single day. Last month she laid 30 out of 31 days!!!
I love all breeds since I love all chickens, but if I have to pick a few favorites, it would be Silkies, Frizzle Cochin bantams and smooth cochins, Belgian D'Uccles and Polishes.
