One of my Tolbunt boys as chicks - (can't find my photos of the other boy)
They were near perfect in color as chicks. Basically brown with hints of black, just as a gold laced would be, but with white (symbolizing the mottling) The white must be both on the head somewhere and the underside. Too much white on the crest as a chick means too much as an adult though. One of my chicks was born with less white, and honestly, grew up that way, which was a desired trait. Most Tolbunts have way too much white.
I don't have any pre-teen photos of them though, sorry. At that time my camera wasn't working. They were mostly brown with black partial lacing, and had white patches on the breast and a little in the face.
To me, an ideal Tolbunt chick color is with very little black, but not too little that the brown is too light. The brown needs to be a modestly dark color. This signifies a more balanced, well laced patterning.
But color isn't everything.
As always said by many, one must build a barn before they paint it. I know the color is what makes people want Tolbunts, but I'm always for the body too. I know my boys have faults (one moreso than the other, but I'm keeping both) but I'm working to fix those faults. One big one to me, which can be identified at birth, is a lack of a good vaulted skull and/or too small of a crest. Next in line are issues like the tail, the comb, the body, etc. And of course, health.
