Thank you for the compliments everyone, she sure is a looker. She reminds me of a baby eagle while the hubby calls her Happy Feet!
I'm not definite if the feed store we bought her at breeds their own stock entirely, but they do have plenty of breeding pens set up and many of their "not for sale, breeding only" pens were filled with Silkies of every color imaginable. I'm curious to find the genetic outcomes of Silkie crosses to determine how many generations it would take (if possible) to have an absence of a fifth toe and leg feathering. Having only online pictures to compare, she does strikingly resemble a blue Silkie chick minus those particular features.
I considered a Blue Sumatra which she also closely resembles except that all the reference pictures to blue chicks show significant facial mask markings and white wing tips. However, seeing how Sumatras have erect tail feathers, it could explain why Tallulah has such a prominent pointed tail compared to the other three chicks (BO, RIR, BR) who have very rounded fluffy rumps.
@dretd: Thank you for the photo compliments. From 2008-2011 I ran a rattery (breeding and showing pedigreed rats, not reptile food) and learned the secrets on how to get clear close ups. The key ingredient is lot's of patience and assuming what their next move will be. Baby chicks are nothing compared to 3 week old rats in the midst of their popcorning stage! I do also highly recommend the Samsung TL205 for it's smart feature and fast shutter speed. I used to have an Olympus model that just didn't cut it before I tested out new cameras. If you're in the market for a new camera, try Walmart. Best Buy takes a restocking fee out of your refund or exchange, but Walmart has a full money back guarantee for 30 days, so I tried a new camera every month until I found the one I have now.
