Know the feeling well about mud and rain!
We rake out old bedding to make a lake of straw in front of pig houses and then replenish house with new straw and finds this helps a lot, we're lucky we can bring ours into the yard.
Hope you get some buyers, might be worth posting in market place too!
All the best Mandy 
Thanks as a newbie I hadn't even noticed the market place!!!
With the pens we set out six new pens last year, each one 30m x40m hoping that being large they will survive the vagaries of the weather, as with many others we thought the better weather was with us. Now we have 6 pens, 18inches of slop and can hardly able to get in them to re-bed the shelters. We built two new pens last week and moved the weaners and their mother into them. Three days later and the're as bad as the others.
As I've said more interested in the welfare of the pigs at the moment than our own (making money).
I'm in the process of putting in planning for a piggery so we don't encounter these horrible conditions again.
