Well-developed young rabbits are well-proportioned, muscular, with no prominent bones on shoulders, back and hindquarters, but their chests are wide and deep, and their backs are also wide.
Check nutrition
Well-nourished young rabbits have plump muscles, smooth fur and inconspicuous bones, and can weigh more than 500 grams when weaned.
Look at the posture
Healthy young rabbits have natural posture and flexible and coordinated movements. When crouching, the forelimbs are straight, and the hind limbs are placed under them. When sleeping, the eyes are closed and the breathing is weak. I often lie down in summer, stretch my legs and squat in winter.
Look at the spirit
Healthy young rabbits have round and bright eyes, lively eyes, strong vigilance, no secretion and active ears. Their ears will stand up when they encounter special sounds.
