One of the pharmacists that Alyssa works with figured out that 1.4 or so teaspoons is approx. what we need to be dosing the hens with in a gallon of water. I don't remember the name of the medication we tried, it's downstairs in the fridge, but it's working! Big Red's eyes are both open, the swelling in her cheeks almost all gone and she was scratching up a storm in her cage today! Big Blue was sneezing yesterday but today I only heard a few birdie "achoos!" so it sounds like she's also feeling better. The other four hens look fine.
Original symptoms were closed eyes, puffy cheeks and a little lethargic. However, once we flushed her eyes with saline, Red was happy to eat and drink up a storm. She could see just well enough to be able to find the water and food we put in her cage with her. Today had her up and about with both eyes open and only a little drainage out of one of them, which was gone by afternoon along with some residual cheek puffiness on the same side. Red is our friendliest hen and we're awfully fond of her. She follows us around the yard like a little dog and loves to be patted.
