If you look closely, you'll notice that the central toe of the right foot is swollen compared to that on the other side. Chaffinches are particularly susceptible to a disease called viral papilloma which causes swelling and deformed feet but I'm not sure whether that is what is causing this. Maybe it's the result of an injury.
