I have a 3 year old wether here in snowy Maine that I found three days ago lying down with head upright, breathing heavily, grinding his teeth, and foaming at the mouth a bit. The galvanized can of chicken feed had been nudged out from under a heavy table and the lid pushed off. I had sprained my ankle and because my husband had to go out of town, he moved it to this new location so it would be easier for me. Wish we hadn't done that. I suspect he got into it, but didn't actually see this. It does contain copper. I immediately drenched him with water/oil/baking soda, put a stick in his mouth... It seemed to help a little in that he was up and about a little more. The next morning, he re-joined the rest of the herd, but was still lethargic. He is drinking water and has pooped, although they are tiny turds all clumped together. Now he tends to stand in front of the salt lick and licks it. He hasn't eaten any hay in three days and is lethargic. I gave him some NutriDrench (only 15 ml in case it wasn't right for him) last night, and today I gave him 20 ml. He weighs between 85-95 pounds. We checked his gums and eyes and did not see any yellowing. I'm not seeing any improvement. I'm beginning to run out of hope and ideas.
