I caught one of my 4 week old Banties and one of my 8 week old Silkies (seperate housing) trilling like song birds this morning.  Nothing remotely like a crowing sound. Is trilling a precursor to crowing?  Do chickens make prettier sounds than I was aware of?  Definitely saw each of them doing it - not just a passing bird.
