I'd seen where some with super early crowers theorized that as well, but I'm not so sure.

The meanest cockerels I ever had (the Marans I mentioned before) started crowing at a pretty normal age, I believe 8 weeks or so but I'd have to check through my thread and see if I said anywhere there to be sure. Those Marans genuinely made me fear for my safety entering that pen. They became soup because I couldn't justify letting anyone else take on such aggressive cockerels even with full disclosure of their behavior.
I think I probably am more lenient on their 'ugly' phase because of this beast of a Brahma cockerel I had some years ago. Compared to this half-naked mess of a dinosaur, none of them seem all that ugly to me during that phase anymore
