'Fancy' Pigeon

Hi everyone,

I have a bird feeding station set up in the garden but it's been attracting a hell of a lot of pigeons and all of the 'mess' that's associated with them. As a consequence, I have reduced their feeding opportunities and limited it to feeding the finches, tits, blackbirds, etc.

However, this 'fancy' pigeon turned up with its 'cousins' about a month ago and has been here ever since. In relative terms it is quite docile and sits outside on its own, seemingly waiting for food. 

My concern is has it become over-reliant on getting food here? As soon as I give it some seed, the other pigeons appear in their dozens and my aim is to discourage them from using our garden as their toilet facility. If I stop feeding it altogether what are the potential consequences? It's almost like a pet and even waits for me to come home from work each evening and is there, on the gate post, every morning.

Advice much appreciated (no tag or band on its leg by the way).
