I get the same non distinct hennie colors when the bird is less than 1/4. They always seem to change out about 6mo, it may just be the strength of the gene. I feel when it shows in a straight feather line and not bred for the line tends to be superior cutters.If in fact hennie colored I am seeing, then likely from a novel mutation. I have never seen proper hennie colored in these birds but many on male side very slow to come into color.
Crappie problems preventing me from getting pictures.
