Yes, the hen did hatch them; 12, but 1 died the first night. The other 11 are doing well and growing fast. Serama make great foster parents, We've used them to hatch and raise turkey, large breed chickens, and now quail chicks. Of course with their small size they can't brood many large eggs; only two or three. Definitely humorous to see a little serama with turkey chicks who soon were bigger than mom.
