I also have serama, smooth, frizzle & silkied. I treat mine the same as any other chicken, bear in mind I live in N CA. They teach themselves quickly to go to coop at night, I had 3 hens go broody together, you never knew who was sitting on the eggs and they all fought over the chicks when they hatched. When you walk into their run, they just stand and let you pick them up. Very sweet little things.
The drawbacks............I find them difficult to hatch shipped eggs, the rates are quite low, but high for incubating your own eggs.
And dang, this season i raised nearly 20, got 3 pullets, yikes!
I do have one little smooth cockerel with a permanent home.. I had eggs that were nearly 3 days past in the incubator, I pulled them out and set them aside. A day and a half later, I was putting the bad eggs in a trash sack and thought I heard a very faint sound. I pulled each egg out of the trash and held it to my ear until I found the one making a sound. I chipped the cold egg open and there was a little serama chick. Of course it was a cockerel, but his name is Miracle and he can stay, he is a tiny little thing and obviously has a strong will to live.
I normally open my non-hatching eggs, but was so tired of finding unhatched fuly formed chicks, I hadn't that one time. I have gone back to always looking.
