International Black Copper Marans Thread - Breeding to the SOP

IMG_3706.jpeg
A quick diagram I made to explain the different shapes we use to describe type. A bird is built on constitutional lines, a phrase I’ve only ever seen used in the Welsummer SOP, but in theory it applies to all chickens. These are the lines in which you can line up the keel and back.

I have then drawn in a line from head to the first part of the breast to touch the lower line, then a second line from shank to tail-base.

This creates a shape, which I have shaded. Triangle (aka V), square and rectangle. I appreciate the shaded shape on the rectangle looks quite square, but you just have to appreciate that the rectangle type is longer than the square.

I’ve also included a rectangle type with a hollow breast, showing that type must be complimented by table quality to be passable.

Great drawings, that helps tremendously with visualizing. Thank you.

Thanks.
If you have access to a printer (or know how to draw on photos on your phone), you could always take a pencil and ruler and draw over a picture of your own chicken, and see what shape you get. But that’s probably not necessary, you can just compare it to the drawing.

I thought it would be a good idea because we always talk about shapes but have never standardised what we mean.
