Take heart, Linda - when I moved to the moorland farm with my friend, we took on the resident hefted flock of 530 Swaledale ewes. My friend had worked with sheep all her adult life, so was pretty experienced. That first year we had a baptism of fire! The ewes (and their lambs too) were all over the place, including jumping over our shoulders and once a ram lamb landed square between my eyes! We'd try to shed them in the race and they'd jump clean over whoever was operating the lever...

I could write pages about the management and husbandry issues we struggled with.
But... by the second year, the girls had got used to us and our dogs, and were much easier to handle. Still wild hill sheep living semi-feral, but manageable. It was a hefted flock so they were all born and bred on that farm and had never been handled by anyone but the farmer who sold the farm to us, and never been driven by anyone but him and his dog. It took them a while to get used to us and to begin to feel confident and safe with us and our dogs.
I'm guessing that your girls will feel much the same, compounded by any inexperience and subsequent less-than-confident-and-effective handling on your and your OH's part. You'll all get used to each other and it will get easier.
Hang in there!
But yes, get some OSBs while the iron is hot!
