I can't advise much, welshlass, being in about the same place myself, though with just the one (hopefully now in-pig, will know more by next week...) gilt.
I don't know if you would be wanting to sell weaners or fatten all the piglets yourself, but I have been thinking about how it's going to be trying to sell weaners just before Christmas and it is not perhaps the ideal time... Not much choice, though, Meg being now 12 months old and everyone's advice being don't leave it too long to get her in pig. Ah, hindsight, what a gift that would be ... though frankly, I think I would still have got my two just as soon as I possibly could after BH finally said I could have some...
