Uninvited guest

We went to Featherville for the weekend and we were a little surprised to see a new addition to our flock when we got home. Barry thought that this rooster may have wandered over from next door, but he didn't belong to the neighbor. Then we thought my dad may have something to do with his arrival, but he says no.
So we have no idea where this mystery chicken appeared from. On a side note, Barry was wondering who was interested in joining us for enchiladas on Sunday?
