Total You've Been Framed moment this morning. The field the sheep are in at the moment has some old wooden fanks, which are partially collapsed, but when I got down there this morning and saw one ewe was slightly lame, I got her into them and shut the gate to the little catch pen. Ewe promptly hurled herself at the gate, which disintegrated and shot out again. Bribed her into the longer, thinner section, left her happily eating ewe nuts while I blocked the entrance with a thorough criss-crossing of a lunge rope across it - ewe went straight through it. Untied it, got her back in, caught her under the chin (she's pretty tame) - success! Tried to turn her on her bottom to check feet, ewe broke free (she's about 80kg, which is rather more than me), I ended up with one arm around her neck and one hand holding the front of her shoulder, being dragged down the field on my stomach until it struck me it might be sensible to let go, as we were heading for an old tumbledown wall and she was planning on going over it...
Feeling a bit like Wile Coyote trying to catch the Roadrunner at this point, I decided to take them through into the little grass patch in front of the byres and hope that no-one challenged a fence as it probably wouldn't take it and they'd be straight out onto the common grazings. After a few circuits, the ewe looking considerably less lame with every one, I finally got her with my crook and decided that rather than try and turn her again, I'd just pick up each foot horse-style and hope that if I kept a firm grip she'd decide the game was up, which she did, thankfully. Found the problem, I hope, trimmed out the pocket (stabbing myself in the thumb in the process), sprayed it, checked the other three feet and let her go.
She promptly came and mugged me for sheep nuts, so hopefully no hard feelings on her side - I'm feeling somewhat battered and bruised!
