Bird ID please

My wife works at a veterinary clinic. somebody found this bird on their doorstep and brought it. Her manager texted me these pictures for an ID, but I have no idea. It certainly doesn't look native. At first I thought it was gull-like until I saw the bill. Perhaps it is a pet. Anybody got any ideas?

here's another one

I believe it is a domestic pigeon, one of the feather foot breeds.

Buck, it is a Pigeon of some kind, probably domesticated

Not in my field guide.
I'd never seen a pigeon with a bill like that, but now that I've googled pigeons, I found some that look somewhat similar. We recently had quite a number of never-seen-before razorbills here, so I thought it might be some exotic accidental.

Thanks
