Answer
im sorry I really dont understand what you are telling me or what yor question is. If your horse is ill and not acting right, you should get an equine vet to examine it. You have not given me any information that is specific for anything other than the horse maybe not feeling well. Id be happy to answer a question if you have one, but I dont understand what you have written. What does day 1 mean??
