Identify this Pigeon?

This is a pigeon we have lovingly named Chigeon (Chige for short), because he looks like a chicken while obviously being a pigeon ahah.

He has been visiting our garden for months now and it’s gotten to the point where he comes when we call and gets really excited to see us. He hasn’t yet got the courage to come and sit with us yet, but we’re trying!

He is the same size as your regular ol’ pigeon, and even though I’m saying “he”, we just assume he is because he keeps trying to woo any lady pigeon he can. (To no avail) He has a little purple tag on his ankle, so we assume he could have been a racing pigeon that has gotten lost. Our neighbours also assume so.
