The dosage is in post 12 and 14. If you could get Tylan (tylosin) powder for the water from a pigeon supply, you could give it in her water for 5 days. Here is one place that sells it, and dosage is 1/4 tsp per quart of water:Hello, I know this thread is a bit old, but I am looking for Tylan 50 directions, too, and stumbled on your post. My hen looks much the same but not quite a swollen. I started Tylan Sunday but only 1 dose a day. On here it seems I should be doing it way more often. 2 is the most I can do with work, so I'll try morning and night....any update on your girl? Did she recover? I can't put my girl back with the flock until her eye is better because they pick on her... wondering how things went for you?!
