I'm glad the honey seems to be working! As far as hydration goes, he may just not be thirsty. They can get quite a bit of hydration from fresh food. If his poops look hydrated then he is probably getting enough. It's still good to offer water in case he wants it, but I wouldn't be forceful about it. Some of them will drink from a water bowl after a while if you flick at the water and create some movement so that's worth a try too.
