bummer about Aubrey. It does sound like his heart is slowly failing. 7years is a good long life for a rooster.
I rather hope they all get to see one last glorious spring.
very cute.
I agree with your guesses as to sex, hopefully and maybe, BUT they could both be male, one just faster to mature than the other.
I can't ever tell for sure until those rooster feathers start coming in.
As to color. no help here, sorry.
I think all of the feathers looking so different makes it a very attractive color.
Not sure I can label it my absolute favorite though....I like so many of them!
