Since this has only affected my meat birds, I figured I would try here. Searches in the Disease section kept efering those asking back here anyway. My 12 Cornish Rocks are almost 4 weeks old. I lost 1 in teh first few days, a second around the two week mark. Listlest/lathargic, white discharge from vent. For the past few days, a limping meatie started showing signs of the white discharge with no normal droppings. I culled it his morning. I move the tractor several times a day, and i will be disinfecting waters and feeders etc in a few minutes. Any suggestions, warnings or things I should watch for beyond others acting similiar? the rest seem to be healthy, free range fine etc.
