Hii my horse sky gets really bored and grumpy in the stable during the day so she has a hard tough ball that she pushes around and treats and feed trickle out of a hole. This is great fun for her, may not be too god for a smaller stable as they may take it into their bed bed but as sky has a big stable she keeps it at the front so she makes sure that she picks up everything that comes out i also hand pieces of bread, swedes, carrots around her stable and hide them in corners for her to find, this seems to keep her amused, as for likits, they are not very good especially as the horses eat them straight away, but also they are fullof sugar and water so can make the horse hyperactive if it is stuck in the stable. Apples in the water are a good idea for amusement and also to stop the wtaer freezing over as it moved it stops the ice freezing, i would watch the horse though if he is new to it. Hope this helps Naomi..x
