I wanted to pop in about my last March hatch - the BBS silkie eggs that only had three out of 18 survive being shipped.
I had three hatch, although two had to be assisted. Two are doing ok, and it turns out they aren't so much "silkie" as "well, most in the pen are silkies", and are both frizzled. Third chick had a horrible horrible hatch, and has some pretty badly deformed feet that I'm still trying to fix with corrective taping. If it survives it is going in my pet flock, I don't want to risk passing on a genetic defect. I'm tempted to ask for my money back, but I'm letting it go....
