Not sure if you know, but there is a Swedish Flower Hen group on Facebook.
Seems to be quite a lot of very knowledgeable folks there.
I have a mixed flock. I just enjoy the variety. I have one SFH who is still just a chick... 4 weeks old. But she is a total stand out in my brooder of 9. She was very weak when I got her home, super wobbly, seemed unable to walk and was falling over. I got some vitamins into her (focused on B vitamins) and she came around fairly quickly. Her feathers are starting to come in now and it is especially fun with her because I can't even begin to guess what color she might be as an adult. Every day seems to be a new surprise. Personality-wise she is most most forward and most brave chick by far. And the mix is a tame friendly bunch... Cream Legbar, Orpington, Ameraucana, Sultan, Polish, and Jersey Giant.
In any case, I am really loving this brood!
