I lost one of my 3 ewe lambs tonight... Glisten (Ash x Vianne).
I found her sprawled in a corner of the barn at 6pm. She was still able to stand at that time but she was breathing heavily and had a racing heartbeat. I had my own foreboding thoughts on the matter, and a call to an experienced shepherding friend confirmed my two suspicions: pneumonia or being crushed/hurt by an adult ewe.
Clancy and I administered the proper dose of penicillin for pneumonia. And since she seemed unable to stand, we also gave her a 0.1 dose of selenium. I didn't think deficiency was the problem since she had been active since birth. But I wasn't overly hopeful of saving her so I decided to just do whatever was possible.
We also milked out the ewe and Clancy bottle fed her just a bit while I went back to the house to prepare the shots. He said the feeding didn't accomplish much except to exhaust her. I was going to take her to the house for observation. When I was removing her from the pen, though, she kept calling to her mama. So I left her in a private stall with just her dam, thinking the mothering bond would be better for her than anything else I could offer.
A few hours later she was gone.
It is hard to lose a lamb.
I could elaborate... but there is no use.
