No two birds molt alike, in my experience white birds often have the worst looking molts. My delaware looked positively moth eaten much like this girl while everyone else just shed feathers she disintegrated for lack of a better word. The regrowth was also very patchy and took a long time compared to the others. I upped her protein quite a bit to try and hurry it up, it helped a tiny bit.
So those long spears with straggly traces of feathers are normal? That's how some chickens molt? They don't lose those long wing feathers; they just kind of get weird looking?
She's hideously cute!
