I've just mowed the lawn and found a baby frog ( half the size of my thumb) in my garden. It was hopping about in between my decking. My neighbour has just filled his pond in, guessing this is where it's come from as we have no pond and I don't know what to do with it? Apparently you shouldn't mover them and they don't need water? It's just so small and I'm concerned he'd still be in neighbours pond if he hadn't been turfed out. What should I do?
