Jones suddenly started limping yesterday and I saw her pass a soft stool, but she later laid an egg and was able to grip our finger tightly with the affected foot. I put a droppings board in the house overnight and found a watery dropping on it this morning. She is also breathing heavily and today is spending time alone. None of the other four is affected. On Sunday we wormed the llamas with Ivermectin/alfalfa cubes; one of them spat out a part of a cube on the ground, but we couldn't find it amongst the leaves. I am afraid that Jones found/ate it. I asked the vet but he doesn't think it would harm her. The bantams came to us late last summer from a responsible breeder. We see no indication of worms in any of the droppings. I think this is urgent any advice please?
