Yes, some of the runners had more dished bills and the heads looked different - eyes further back.
I'm no Indian Runner expert but they certainly looked different to what I have seen in the UK.
I took lots of photos - as most birds had wide bars on their cages, you could just about squeeze a camera lens up to the bars and take a photo without flash if they were calm enough. The runners however were much more difficult, being more nervous, they had a barrier 3 feet away from the cage front to stop you from getting too close and startling them so I could take a limited number of photos that were any good.
Sorry to hi-jack your post Rooster! I will post photos under a separate post in the Showing Waterfowl section once I have had a chance to go through them...
