In Spiritual methodology, from biblical stand point, there's  what is called the Law of first Mention. The law of first Mention state  the implications, meaning and expression given to a word at where it was mentioned first. That meaning or impression can be used to interpret any other reflection of that same word or phase.

(Now  I have established this)

The first time the word cock crow was mentioned in the whole Bible was In Matthew 26: 34 and it's says 

Jesus said unto him, verily I say unto thee, that this night, before the cock crows, thou shalt deny me thrice.

(Forgive me and just follow me, I'm a teacher of God's word so I have to break my point, to the way everyone here will understand, don't forget we reason differently)

Okay! Following the movement of Jesus in various places, it's began in Caiaphas the place of the high priest Matt 26:3, then He move to Bethany the house of Simon the laper. Matt 26:6, then move to Galilee Matt 26:32, then Jesus move to Gethsemane Matt 26:36, then finally they led him back to Caiaphas the high priest place.

 ANSWER: THE COCK THAT CROW TO CONFIRM PETER DENIAL WAS OWN BY THE PRIEST  Matthew 26:58.

Thank you
