I have been breeding silkies for a couple years now, and I personally really love the breed. They're very friendly, which makes them good for showing, and great at hatching their own chicks, which frees up the incubator during spring. One thing I have learned is to really learn the good breeders before getting birds, which is a mistake I made a couple times. But of course, you've probably learned this from the breeding you currently do. A great breeder is Magnolia Silkies, and I am currently trying to get some birds from her.
I also recently started breeding seramas, which I also love. They're super tiny, so easy to make room for, and when hatching them, you'll get all different color varieties. With silkies, I was getting a little tired of the same white feathers, but the seramas have a lot of variety which I love. I'll breed two birds with the exact same colors, and get something completely different. Of course, if you like getting the same color, seramas might not be the best choice. They're also very friendly.
Those would have to be my two favorite breeds out of all the bantams I know much about, although I might be a bit biased. Good luck with your breeding program and finding a new breed!
