I was right about not getting much sleep but she looked ok every time I checked on her. This morning her sides look less swollen and she is moving more. She's had a small amount of Readigrass, some sugar beet and a little coarse mix. I did manage to tempt her with some branches as well but only a few leaves. She is cudding though and I shall keep offering bits during the day.
Thank you for all your kind comments and especially to beeducked for all her support.
