H Jeza! Bees stop flying below about 8-9 degrees Celsius, or if there's no forage, so perfectly normal to not see any activity during the winter - they're smart and conserve their energy when it's cold and there's not much to eat.
If you do want to separate the honey from the wax without having to purchase an expensive spinner, you can just crush it and put it through a sieve. A lot of honey stays with the wax if you do that and, because it's a terrible thing to waste, you can wash the wax and use the honey water to make mead, then use the beeswax for candles, cosmetics etc. I'll do posts about all that sort of stuff too.
Feel free to ask questions, always happy to help a fellow beekeeper and I'll follow along to see how you go - good luck!
