Well, BYCers, y'all were right. Cinnamon was a boy! The pictures I took of him last night, when he'd been caught and packed up to be rehomed at our preacher's house, don't do him justice. He really turned out to be a beautiful bird, and he was just getting protective of his hen--Sugar was the only one of the pullets he hung around, which was to be expected, since the 4 little ones were raised separately--and followed her around like her little puppy!
Sugar definitely seems to miss him, this morning, but from what I've seen so far this morning, she's going about her activities like she normally would.
