Thanks for the advice
I think by the things you have described, it could be a combination of things - He has changed pellets recently (Both he and the pigs get bored after a while and I have to change them or they simply don't eat them), and the caecotrophs I have removed
have been a bit smelly, though he's not leaving them every day.
So I think I may up his hay intake and reduce the amount of fresh produce to see if it helps, and I'm going to trouser clip him to prevent the fly-strike (I bought a set of dog clippers and they work well, and Tila's a good boy who sits still thankfully), and I'll see if I can obtain some rear-guard from my vet.
Also, he is due to be wormed again. Could this be another reason? I have not seen any visible worms in his droppings, but could there be some in his gut making the bacteria imbalanced?
Edit: He has only started doing this in the last month or so, and he had a full dental on his molars in the last few months. Usually if he's having tooth trouble he goes off his food and gets very grumpy, but he has been eating well and romping around happily. I will keep it in mind though
Edit 2: If it helps, his diet is a handful of pellets a day, unlimited lucern and oaten hay, and a variety of small amounts of coriander, dill, mint, capsicum, cucumber, brocolli, carrot, apple, pear and banana, occasionally some other veges or fruits but those are his favourites (definitely not all of those in one night though, only a few each day :lol
