Natural Hatching. Natural hatching under a broody hen is the ideal way to raise a few chicks and children love the experience. It is, however, essentially dependent on having a broody or broodies at the same time as the eggs you want to set.

As nouns the difference between hatching and crosshatching is that hatching is a method of shading areas of a drawing or diagram with fine parallel lines while crosshatching is (arts) a method of showing shading by means of multiple small lines that intersect.

The hatching lines differentiate the areas which are cut and those areas which are not cut by the cutting plane. The purpose of showing the hatching lines is to tell the observer as to where exactly the imaginary cutting plane cuts the material of the object, as it slices/passes through the object.

Crosshatching is an extension of hatching, which uses fine parallel lines drawn closely together to create the illusion of shade or texture in a drawing. Crosshatching is often used to create tonal effects, by varying the spacing of lines or by adding additional layers of lines.

Cross-hatching is a method of line drawing that describes light and shadow. The representation of light utilizes the white or openness of the page, while shadow is created by a density of crossed lines.

Cross Hatching is like taking parallel hatching to the next level. You create a first layer of parallel lines (in any direction) and a second layer of lines is drawn on top in a perpendicular or nearly perpendicular manner.

With cross hatching you are drawing parallel lines, varying the direction of the lines and layering them to obtain different intensity of shading. I like to start by the lightest area and then add layers of cross hatching until I reach the darkest area of the drawing.

Elements of shading:

• Shadow edge. This is where the object is turning away from you and is lighter than the cast shadow.
• Halftone. This is the mid-gray of the object.
• Reflected light. The reflected light is a light-gray tone.
• Full light.
• Blending & Rendering.
• Hatching.
• Cross-hatching.
• Stippling.
