Thanks as I was wondering seeing as how sensitive some of the top knot breeds are to a single peck, I noticed in the pictures I have seen the feathering on the head is less pronounced, is it ever a problem that requires trimming like in some more ornamental breeds?Toppies I have had differed only in the feathering on the head. You could discern homozygous and heterozygous individuals based on appearance. Neither exhibited a soft spot in the dome of skull.
