When I ordered from Cackle two years ago, I ordered 30 Silkie chicks. I ended up with 33, and I only lost one within a day, but he was small. I took them to the county fair and didn't win anything, but they have all been very healthy so far. I ended up selling over half of them, but I still have 14 from the original batch. They are all healthy and happy.
I probably would not order from them again though. About 10 of those chicks had extra toes (6, not 5), and about 4 others had curled feet. I ended up with very slim pickings for the county fair, since I had three different colors. They did accidently slip in a splash rooster though. He is pretty sweet.
