The 2nd one looks like a frizzle. That's what mine looked like when they were that age. Also count the toes. Silkies have 2 toes in the back, cochin frizzles only 1.
notwe did get them from TSC. We have hatched silkies before. that's not what they are. They all have clean legs too. The closest we have found was blue Dutch bantams. still not exact though.
