Thanks Shep, Realised she didn't jump the fence, clever little B must have remembered the gateway way down the bottom of the field I'd brought them through previous night, I'd pulled and tied the stock fence back across, but she pushed under it, did it another twice before i saw her coming up the field instead of across. Sheep hurdle cured that little trick.

.
No blood on either of them, her vulva not pink and swollen, but sure she's not due for at least 2 wk, but the other one is, as to standing over them facing the tails, my legs aren't long enough and I don't fancy being taken for a ride round the field, (texel or a big texel x, acquired as a lamb).
I can't really leave the lamb on anyway, I'm giving it a week to see if its front legs develop more movement, obviously can't walk round much. It will be difficult though, she's quite a little character.
Main concern now is mastitis, if Gemma is not the mother, then I don't want to be milking her out?
She does look to have a full udder, but wouldn't that be in response to the lamb taking her milk?
I'll have another look at her in the morning, if I could be sure she had lambed, I could probably get a lamb for her.
