Well, its bad news I am afraid.
I upped my visits to the barn to one an hour, then looked after 45 minutes. She was still lay in her corner, but not looking distressed. Been to look again, and there was a kid lay there. It did not appear to be moving, so I grabbed it, and did everything I could to revive it, but sadly no use. Charlie had cleaned it, and its mouth and nose were clear. Such a shame, big strapping billy, black and white, the image of Bobby the billy goat.
Charlie is now tucking into her hay, and does not seem particularly bothered to me.
Not a good week for me, as yesterday I found one of my cats dead which was a shock, and now this. But, keeping livestock involves lows as well as highs, and we just have to accept it, don't we.
