A friend of mine just started raising chicks. She bought some buff orphingtons from a backyard seller and then bought some more from another seller. The Buffs started with the bloody poop and died. Then more bloody poop and I imediately told her to start with the Sulmet at 1 and a 1/2 tsp in a quart of water. It has been 4 days and they are still dying but no bloody poop. I told her to totaly clean and disenfect the coop wihich is a converted brnd new rabbit cage. What else can we do. Is there a different med we can give. The chicks range from 5 wks to 3 wks. Any help would really be appreciated. This is a heck of a way for a newbie to get introduced to chickens.
