Hi I have two Indian runner ducks one of which i raised and the other one was recently bought. Both have the same stance, but don't appear to look anything like the ones on the internet as they don't stand up as straight, the drake is a bit fatter then the ones on the internet. So i was wondering if theres a chance he could be crossed with a pekin. The only time he stands up like the ones on the internet is when i call him or he hears something. Thanks .
