What to do when a sheep is found cast (lying on its back with its legs up). I worked as a shepherd & had to do this quite a few times. First of all, try and find a farmer to inform them of what has happened. If no farmer can be found, then you need to approach the sheep calmly and gently roll it back on to its feet. If left in this state for a long period of time this can mean a slow and painful death for sheep through suffocation. | Get Wild
