What condition defines a rabbit as "not well filled out"?

The condition that defines a rabbit as "not well filled out" relates to the body shape and overall appearance of the animal. When a rabbit is described as "choppy," it indicates that the rabbit has a disjointed or uneven body structure, lacking the smooth, rounded contours that signify proper development and health. A well-filled-out rabbit should have a uniform appearance, with muscle and fat distributed evenly throughout its body, contributing to a robust and healthy look.

The term "not well filled out" traditionally ties to a lack of fullness in the body, with "choppy" describing a more specific aspect of poor conformation. An underweight rabbit may also appear less filled out, but it is not solely about the shape but rather about the overall condition and balance of the body. Choosing "choppy" thus emphasizes the irregularities in the rabbit’s body shape, making it the most fitting answer for the question regarding how a rabbit may exhibit an unappealing or poor physical appearance.
