The chicks are somewhere near the end of three weeks of age, near as I can tell.  They are getting their feathers in and are becoming less hand shy.  I began dumping a bit of chick starter in my hand and they have begun to come and peck away at it.

The Buffs are super friendly.  The Amerecauna (figured it out) Easter Eggers are a bit gun-shy, but are starting to come around.  The coop is looking fabulous too!
