Yeah, he looks nothing like her and I wouldn't consider him a good candidate to prove anything out. Still gonna hang onto him to see if that mustache is genetic, though. Too weird that 4 out of 6 hatched out that way.

As for the dam, her head/neck have had that blushing for as long as I've had her, but it seems to have gotten a little bit lighter over the years. I didn't get her until she was already a subadult, so I have no idea what she looked like as a youngster.
