There is a field of oilseed rape two fields away from our house. There are beehives in the field that aren't normally there so I assume they've been put there to feed from the flowers. Quite a lot of bees have been coming to the dog's bowl for a drink so I've put out a few safer dishes for them to drink from. There is no other water source at this time of year apart from a stream about a mile away in the other direction and whatever water my neighbours have in their gardens.
My question is should the bee keeper not be providing them with water or will they always find a natural source, no matter how far away it is?
