Well, we are on day 7 of corid and I'm still seeing blood in poop. I think I'm going to try and collect another sample or two soon and take them back up and look at them again. Also going to try and give the 3 sweetgrass a corid undiluted drench too. I keep thinking what if it's just shed liner? I don't think they shed liner almost daily though, do they? These happened overnight, which I hear is when they are most likely to shed liner, but I'll keep an eye out and see if I find anymore throughout the day. I'm about to just buckle up and take them to a vet to pinpoint what's wrong because trying to guess on 3 different things is so stressful lol
