It looks like my sick pullet has some sort of respiratory ailment. She's breathing heavily, is chirping and has her feathers ruffled. I picked up a pack of terramycin this morning at the local feed store. However, it looks like the dosage is 100 mg per quart of water. The entire package is 181 grams. Any tips on measuring terramycin. I asked my dairy farmer friend what he does, and he laughed. He's never dealt in that small dosage before.
