As many of you know from the members section, I have taken on two new ewes (about 10 months old)
Congratulations on your new sheep!

If they are pregnant I know I will need to be on hand as they are young and I am putting plans for lambing experience into action as we speak.
Godd on yer gal

Because of the fact she *might* be in lamb I was going to collect some poo and give it to the vet tomorrow for a worm count rather than re-worm her - does that sound OK?
Because you have the vet coming anyway, best thing is probably to ask his/her advice; they'll know what's likely to be about in your area, whether there's any resistance to any drugs, etc. I would hesitate to advise anyway, conditions where you are would feel like summer to me!
I assume you are not in a flukey area? If you are, definitely fluke them both - you can't wait for symptoms with sheep with fluke, you need to keep them fluked - but quite likely fluke is not an issue where you are. The vet will know.
Was going to wait until dry weather June time for shearing? is that ok? Dagging - was goign to try and do that sooner rather than later due to runny bum situation but waiting for dry days? Do they need dagging before lambing? (if they are pregnant!)
Up here generally lambs are not shorn in their first year, they are shorn in their second summer when the fleece is ready (the lanolin is rising), after which they are known as 'shearlings' or 'shearings'.
I would clean her up (dag her) before she lambs, yes - you want her clean for when the lamb(s) are born and trying to suckle.
HeptavacP - 4-6 weeks before lambing or one year from last time (which was april last year) - am I right on that?
If they're pregnant, they need it before lambing to pass on passive immunity to the lambs. If they are not in lamb you could wait until April for an annual booster, or do it now, or any time in between - if you are keeping them for breeding, they'll be getting their annual booster before they lamb next year and if you were not going to keep them on after they've had any lambs they're carrying now, they would be away long before next January.
I will phone animal health tomorrow. I have a herd number for goats, do I need different flock number for sheep?
Yes I think so (but I don't have goats so I could be wrong on that.) You may also need to do some paperwork to transfer ownership to yourself, you will probably have to ask Trading Standards' advice on that one, or just do an AML (movement license) where the holding number stays the same but you sign as 'receiving keeper' at the bottom.
still lots of very green grass so not supplementing with hay until/ if we get hit by snow. They get a few sheep nuts and I will be able to increase/decrease depending on vets findings tomorrow.
They may need additional sugar in one form or another for the last two months of pregnancy - our grass has nothing like enough at this time of year, being so far north, but yours may well be sufficient. The vet will advise you. What they would certainly need up here is a mineral drench and maybe a copper supplement but again I don't know your local conditions and the vet will.
Really want to give these girls a chance at a good life so sorry for lots of questions. Have been lent a fantastic book by a friend from here and of course the Tim Tyne one is on my payday purchase list
As has been said elsewhere, these ladies are very lucky to have you to care (so much!) for them - and if no-one asked questions what would TAS be for?!!
I am really looking forward to hearing the vet's verdict tomorrow.
