Your lil helper is so CUTE! Aren't the Serama's so cute!! I love ours so much, and they're so cuddly!
Very nice!
They are their own breed. It was developed in either 2000 or 2001 somewhere in the far East, I want to say Indonesia, and is the smallest chicken breed in the world. They come in 3 feather types and at least 2 body sizes. The feather types are smooth, silkied and frizzled. Body types I know of are (I think) standard and micro. Normally it takes about 5 serama eggs to equal 1 grade A large egg. They are very heat hardy but not cold tolerant, which is why ours are going to winter indoors. And they very prone to broodiness. That's all I remember off the top of my head.
ETA: they're listed under the breeds section on here if you want more info on them.
