Harvesting in March?

At last I got around to fitting guttering and a water butt to the shelter - "rainwater harvesting" in the current techno-speak - it will be much easier and less wasteful to top up the ducks and chickens water, and for watering the vegetables. In spite of the drilling and sawing, the hen in the photograph hopped up into the 'witches hut' nest, and laid her egg - you can't hold back a force of nature. Talking of which, arent' oil rigs incredible? - just watching Richard Hammonds Engineering Connections, a really good programme. I took a step forward with setting up the web-cam outdoors, but it needs a much stronger battery than the one supplied.
