Hello,
I too, am new to Forum. Find your message interesting as I have one Herdwick 7 month old lamb with much the same symptoms.
Lives outside, bought 8 days ago, along with another 5 same age, gender, breed.
On grass, when weather particularly cold given small ration of concentrate. 5 eat it well, one stands back, or walks over to mineral bucket and licks that, she is drinking, sniffs at concentrate, walks away.
She not sufficently brave to walk directly to me yet, the others do, though not hand feeding yet, still very wary of me.
She seems as alert as others, though possibly, unless I am being paranoid, lies down more than others?
?
Not tooth grinding!!
Suggestions?
?? Appreciated,
Thank you for reading my posting.
Hoping that Messyhoose is finding solution.
