Hi Shark,
My seekh kebab recipe is this one mate
http://www.curry-recipes.co.uk/curry/index.php?topic=4393.0You may be able to use the kubideh recipe too, but it has a much more subtle flavour than the seekh kebabs, and it is a little trickier to do, but hey, give it a go.
Just one question if I may Shark, why do you want to use chicken instead of lamb, is it just that you don't like lamb, or perhaps worried about the fat content?
Good seekh kebabs do tend to be more flavoursome if the fat content is quite high, that's why I suggest using minced chicken thighs rather than breast, because they have a much high fat content.
Anyway, hope all goes well, and if possible, post some photo's of your efforts.
Good luck,
Ray
