I think thats a great price for 10 silkie chicks too! I paid $7 for my four so already $28. How did you determine if they are boys/girls? I know silkies can be so hard to sex. Mine I have been guessing by how fast they are feathering in. I also heard of this farmers trick where you hold the hatchling on its back and if it legs tuck in its a girl and if they don't you "give it back" Haha (as in to the seller)! However, so far the ones whose legs tucked in have the fastest feather growth, so he could be on to something!
