Are you sure the Pekin rooster doesn’t wear a no crow collar. Because he sounds as if he has one on.Such a nice feather!
Here is the link of a Pekin rooster crows, it is not loud and he does take a break in between.
I once had a standard size rooster and he crowed a long super loud sound that I feel can cut the sky in half. He wore a no crow collar to ease the sound a bit.
If this is a normal sound for Pekin rooster, Im very interested in getting hold of a few eggs in the future (complete atm).
It will be a hard search bc in the Netherlands they seem to think that Pekins are the same breed as bantam Cochins
