Morning everybody, I have some issues with my almost 2 month old group of light Sussex and buff orpingtons. I had thought they had coci since I had found traces of blood in their feces. I’ve been giving them plain greek yogurt and corid for almost 3 weeks already and this morning I lost two more of my light Sussex and have a buff orpington that is displaying the hunched up, pale face, not growing, symptoms. So far I’ve lost 4 of my light Sussex, I think it had something to do with the fact that I bought the Sussex as 2 week olds and I have no idea if they were on medicated feed or not; because my orpingtons have appeared immune until recently and I got them as day olds and have been on medicated feed since day one. I’ve been separating them, cleaned out my coop, putting a light on them at night (its been rather chilly) plus giving them the corid/yogurt. I’m at a loss as to what to do, any further advice would be most welcome.
