we were down on our allotment until late last night, 10 pm or so, watering, weeding and burning the dreaded Marestail. About 9 o'clock our dog jumped up and started frantically pacing the fence between us and the slightly but pleasantly overgrown plot the otherside. We could see the long grass moving as something made it's way through, eventually a small brown head popped up, which I identified as a Weasel, I suspect it may have a nest? in the compost heap. Delighted to see it, however I have to trust that it will leave our hens in peace, I've seen a few mice and rats on the field so hope it continues to hunt them. I don't think the Weasel poses a threat to full grown hens unless anyone knows different? ( ps our run is rat proof and has 1/2" weld mesh)
