First off, if they live long enough to lamb, in my experience TLD ewes generally come 100% right as soon as the lambs are born.
She's eating, cudding, pooing and peeing (and yes, keep helping her with that - and make sure she's drinking plenty of water too, even though it means you having to help her pee more often!), so that's a very good sign. The ones that die give up and/or their rumen stops working, so she isn't in that category at the moment.
She's hot. Ok - how warm is it in the shed where you have her? Can you increase the ventilation? It could be simply that she is overheated due to her condition, the amount of wool she has on, and the warmth of the indoor environment. (And again, make sure she is drinking plenty of fluids
) Is she on straw? If the straw has been soiled and she's lying on that, she's got a little furnace underneath her - try to keep where she's lying clean and dry
She could of course also have some sort of infection causing her to have a temperature. I'm always the first to chant that we shouldn't use antibiotics without knowing we're dealing with a bacterial infection, but this ewe needs all the help she can get, so I'd be giving her a course of Pen & Strep. And, even though vets and doctors tell me I'm loopy, I'd simultaneously feed her a priobiotic yoghurt to re-establish her gut flora. Again, can't do any harm and IME is really helpful.
