One of our light brahmas (probably about 8 lbs) really did a number on her middle toe. From the after math, it looks like a predator got at her through the chicken wire and she had a compound fracture of at the first (toe nail) joint. We are treating the open wound, but I need to get some antibiotics into her. We picked up Duramyacin powder from the farm store, as that was the only antibiotic they had left, but the dosing instructions are for a gallon of water! I just need to dose the single hen. Can anyone help?
