found one dead white leghorn today. Noticed alot of bloody poop, one really sick hen and a few more that look sick. I've read a few books and i think its that word that starts with a c. I've never had problems with illness b4. So besides that c word illness what else causes bloody poop? How do they get it? I've not added any new flock and they stay inside there pen. How do I cure them? Will the sick ones live?
