I just went over to that thread and it does seem some people have some silkie hens for sale, however thats just too far for me to travel in one day. If it takes me 4hrs to get to CT I'm sure it takes just as long, if not longer to get to the LI area. Its too bad I wasn't searching for these two weeks ago when I DID have a trip to CT planned. I could have picked something up while I was down there. Owell, everything happens for a reason a guess!
The DNA sex testing experiment sounds interesting.
Lord have mercy I've seen silky chicks at the auctions go for $1.75 ea. While do not advocate buying chickens from auctions if you can quarantine them for a full thirty days you might do ok. Chickens sold at auction don't bring enough to cover the gas to get there and back so I don't go.
Anywho, I think you can find some closer to Syracuse.
