Ufff... Especially Knopf... It's brave of you to write about all of it... Heart-wrenching... I'm truly at a loss for words...
Sending you more strength, love!
That nasty nematode... I'm sure you've ruled out the source of the infection. And if not, you will soon. I also hope your herd is free of them as soon as possible. Sending hugs and love.
