One of my 8 wk. old cockerels has been crowing for the last 2 wks. When we first heard him, we thought something was wrong with him, or perhaps chocking.I rushed the brooder with worry, pulled him out to check what was wrong. Well, he did it again; and my husband told me to stop worrying for; he was crowing. Did not sound like a crow; it was like out of tune toy horn. Since that day, he has been crowing, which is the funniest and cutest sound. It is not loud, one has to be in the same room to hear it. I had no idea they would crow at such a young age.
