Hi I'm new here and I'm in a flap. I have 5 saddlebacks, born in January, due to go to slaughter on Tuesday, but this morning I found one of them rather unwell. Her bottom was covered in runny poo and her tail limp, she only ate a little food. This evening her bottom is dryer but she only ate one mouthful then heaved, I think she vomited or dribbled the food out and although she didn't actually poo she sounded very squirty/farty. She then wandered off down the field and didn't eat again.

They've had a lot of apples recently and a few of them were rotten, could this be enough to cause this or should I be worried it's something more serious that might require a vet?
