I have a relatively small paddock 1/4 acre (going to expand) with my horse on it. I'd say there is very few worms in it and her burden would be low. As she was clean when she came as was the paddock.
I don't know how wormy his horse is or is not but if it is then isn't he going to ruin my clean paddock?? I don't want that.
What can I do?
