Our 9 week old rooster *tried* to crow about 2 weeks ago, but hasn't uttered a peep since. Last night we were watching youtube clips about feather clipping and I was holding him in my lap, looking at his feathers when I saw clips titled "rooster crowing" etc., and wondered what the lil guy would do if I clicked on it. He TOTALLY perked up his head and opened his beak SEVERAL times without a sound coming out....then all of a sudden the LOUDEST squawk a doodle ever...and he kept going!! I joked with my husband that I hoped I wasn't setting some unattainable standard by just repeatedly clicking play so the online crow was just playing over an over again. He wouldn't stop crowing until I put him back in his pen and he realized it was night. We got it on video. I am such a chicken nerd.
