So glad you could join BYC! Bantam Cochins are lovely birds. I've kept a few in the past, but don't raise them right now. If you're looking for birds for sale, I suggest taking a look at the Buy-Sell-Trade section: Buy ~ Sell ~ Trade Cochins are a popular breed that I'm sure you'll be able to find rather easily.
Welcome to our flock and good luck with your chickens! I hope you enjoy BYC as much as we all do.
