I expect it can't cope with been in a pot especially one as small as 14inches. They grow naturally into quite large trees trees and even though traditionally kept small at 5-6feet this was with annual pruning and to help harvesting so this gives you a sense of their vigour and size.
i would get it into the ground or a much bigger pot and give it a good feed. You will need another cobnut (of your own or in a nearby garden) to get any nuts as they dont self-pollinate.
they do make quite attractive specimen trees in the garden. Link below to a site which might be useful
PS if you do start to get any fruit just be warned that you may never actually get some yourself. We have established hazels in our (new to us) garden and the squirrels ate the lot last year long before they were ripe enough for us : )
