My sister-in-law and I are raising some chicks. We got 4 (what were supposed to be girls) on May 19 that were about 2-3 days old at the time. So they're about 2 weeks old now. They're over at my SIL's house next door and she just emailed me to ask me to inquire here. She said... "Twice I have heard a noise that sounds like a dirty sliding door screeching open. Ask in the forum how old baby cockerels are when they start making the pathetic noise that they hope will be a "cock-a-doodle-doo"???" Is it possible that one of the chicks is a baby rooster?
