In my world, black based are rarer. LOL! I think all the colors except Snoleopard are readily available. Of course, SFH are still considered as a rare breed.You want to look for this with all over flowering. I like to mix up the colors, just like if they were free ranging in Sweden. You never really know what you will get with SFH's.
I have a non-crested SFH rooster, who is a fence hopper. Ha apparently dallied with one of my dark brown leghorns and now I have the cutest little SFH/DBL cross. He has a little crest and the personality of a SFH. That is a surprise because the leghorn disposition is nothing like the SFH personality.
