1. Stretch – if the calf is lying down when you walk into a field, approach slowly and look for an obvious stretch when the animal rises. A strong stretch is an indication of a healthy animal.

2. Head – the animal's head will tell you a lot. If it's standing with its head below the level of the shoulders there could be an issue, particularly if the animal is also standing with a hump in its back. Are the ears drooping? That's another bad sign. Is there evidence of mucous on the animal’s nose? Is the nose dirty?
