I have 5 16-day-old silkies, all from the same -reputable- farm. Each one is a different color. Four are very fluffy, top-knotty, feather-footed and everything a growing silkie should be. Then there's Kevin, the white one. She had a difficult hatch. I surgically opened most of her egg for her as she hatched two days later than the rest, and her umbilicus wasn't totally healed. Despite that beginning, she thrived and is the smartest, fastest chick. She's really vigorous, and lay fights with the others. She looks increasingly different from the fluffy ones though. She's the same size & build as her brooder mates, but her chick-down is increasingly short as she gets bigger. Her black skin shows through the white fuzz. She reminds me of my chihuahua, while the others look like my Pomeranian. Should I worry that the lack of fluff indicates disease? Does she have a double copy of a recessive gene that could also mean she had other recessive-gene-linked problems? I know only enough about genetics to have my brain make trouble for me. Could a cuckoo have laid an egg in the hen house? Any ideas? Thanks!
