Sadly we lost one of our 5 month old hens on Sat night. Friday evening her comb went grayish white, and by morning she was gone no other symptoms. Since then, we have notices that others in our (now) 8 bird flock have had mucky, soft green manure. Apart from this they have no symptoms... they look like happy healthy hens :? A friend suggested that it might be coccididosis. I picked up amprolium (9.6 liquid) at the farm store, but it is only dosed for large animals. Does anyone have any insight as to what this might be? Or what the "chicken" dose of the antibiotic is?? Thank you so much.
