I only have 6 bantams... so I do pay special attention to them.
I first us a flashlight and put it up against the nail so I can see how far the toe has grown down in comparison to the actual nail. I then clip with a dog nail clipper... leaving a little room between the nail and the toe. I then use Pedi-Paws (which I got for my dogs, but works great for my girls) and sand and shape their nails into a managable length and width.
I have a couple girls whose nails grow wildly fast, and others I really don't have to touch.
