Betty is recovering well physically and I think has finally accepted her foal is dead.She is back out by day with her 2 year old daughter who she still adores and I will put her back in foal but not til next year.
I think the window for fostering is passing now-it would be more stressful now to move her and get her milking again than it is to leave her with her daughter.
I hope it all worked out well for you and thanks again for your support
