It looks like it is coming to a head, thank you for posting that! I have him in the round pen now. Called the vet and he said it isnt something they like to treat at home. They need an ultrasound to find the pocket....which sucks cause I don't have a trailer yet either. So I am searching for someone who hauls horses for a fee or a rental trailer. He wanta to see him in the morning. And I work 12 hr night shifts, so a tad stressed now! Lol. It will work out.
