That is good to know. GFF didn't care for bantams like Seramas and I always saw Seramas as being so delicate -- they are the smallest chicken breed? They are so cute but I don't know how much their behavior parallels LF. Our bantam Silkies and the roo while we had him was every bit as active as LF which is why we rehomed him. I hope you can find your hen - I know what it's like to search for a breeder that has the bird you want. I have to order my bird in the Fall in order to get a pullet by the following Spring!
Oh that whole event was a few years ago, now I have a whole flock of my own =D I'm actually downsizing my serama flock right now to work more on type. I have an incredible little rooster but I need some better quality hens. I was keeping my mediocre hens because they have such beautiful and unique coloring. My one really amazing hen who had beautiful type was also SUPER tiny and consequently she was infertile and never had any offspring of her own (though she hatched and raised other girls eggs). Seramas are supposed to be the smallest chicken breed in the world, but they don't breed true to size and many of them are large. The smaller ones are less healthy and are often infertile, but two "C class" (refers only to their weight a D size, not their type) seramas are just as likely to hatch A class and micro birds as any other size pair. They also don't breed true to color. This crazy random mix of colors and sizes is what I love best about serama! You can better the breed by working for a good type but I could never get bored like I would working on just one specific color.
My seramas are definitely active, and my rooster mounts ALL the hens including my LFs, he's very protective of his flock and is even a really great daddy chicken to all the babies. They fit right in with my LF flock. The tiny hens can even hold their own against big mean LF broodies when they have to LOL
