I have two roosters (really, cockerels), after not having any since I was a small kid (so I'm fairly ignorant of roostery issues beyond the obvious showing them you're top chicken so they don't attack you). They grew up together, and get along well, fighting very little, even when rooster #2 tries to hump the same gal at the same time as the top rooster. But recently, rooster #2 crows and a little squeak comes out instead of a crow. Anyone experience this before? It's hilarious, but I hope not a sign of sickness or something.
