The veterinarian who is in charge of the project has admitted that some days they are dangerous, but we still have to use them for our lameness study. He has ended up just allowing the horse to come at him and whipping them to make them get beck. It worked in the short term, but as I feared it did nothing in the longer term. (as in 3 weeks later)
These horses rear and strike when they want to be done, want to go back to their stall, or hear other horses going by outside of the lunging area. If they do not rear and strike they have a tendency to either try to spin away and run or spin away and kick. I know how to stay out of reach, and I have been using a chain over each of their noses, but they still are willing to try at least 3-5 times each lunging session. These horses do not have as much turnout as I would like, but I have no control over that.
Are there any training methods or ways to cope with them that you feel might work better. I am only able to work these horses about 30 minutes per day, and I am not the only person working with them.
