Well done for sorting out the stuck lamb

Yes, the curled eyelids need reverting - maybe not quite so gently as if you are having to do it more than a few times, it could help to pinch a little to cause a little bit of swelling, which will help them to stay the right way out.
Your post reads as if you have left the shearling ewe tied up. Hopefully I've misread that!
I would put the lamb in a box next to the ewe, where he's safe but she can see, hear and smell him. Then go and stand in with them every few hours to give the lamb a feed. Reprimand the ewe if she butts him. Make sure he gets a feed. Let her sniff his bottom while he's feeding - this really helps her feel bonded.
Then do the same with you not in the pen, then leave them together while you potter about nearby keeping an eye and ear on things... Until you are sure she is over this silliness, don't leave him with her unattended.
