Thanks, everyone. To address some of what a few people said/mentioned...
Her sire was an over-colored roo who had good type but an overlarge comb and a little shafting on his front. Her mother is a decent type with only a tiny bit of mossiness on the tips of primaries, and very little feathering on shanks or toes.
Even if I could breed her back to her sire (I lost him last winter to a possum), I wouldn't because it would mean breeding too much color to too much color. The boy I have all of my girls with now has better coloring, if not lacking just a little bit. I was hoping that might correct the mossiness but wasn't sure if it would actually help.
Tbh I'm a bit disheartened with breeding right now. I've been having HORRIBLE hatch rates since I got my new incubator (like 15% at most), and my Splash Copper pullet that took me so long to get and whom I raised for a year and a half now, it turns out I can't even use her to start my blues. She's always been mean, but I was hoping my nicely mannered rooster would tame down her chicks...turns out not to be the case, as I currently have a brooder full of 5 week old blues who prefer to eat my fingers and a brooder of week olds who are already starting to show the same behavior. :/ I'd heard meaness could carry through generations but I didn't think it would carry through like it does in her progeny's case.
So I've been doing a lot of thonking about what I want to do about all that.
