Does anyone know the dose for this? I don't know what is going on with my chicken. She's been sick now for several months and I've tried everything. This is my last try. Have it on order. She eats, drinks and acts fine except she's had a bad respiratory issue going on and I can't get it cleared up. Her sinuses are swollen. I thought it was coryza but no other chickens are sick. I've had her inside and outside both. She's currently out during the beautiful weather to get her sun and sleeping in the house just to be sure she stays warm The goo coming out of her nose and eyes is smelly and goldish color. Her eyes bubble and gunk up so bad that her entire eye can be covered. It's sticky too. I think her mouth looks ok. Tried Tylan 50, Sulfamed liquid in her water, Baytril (not sure what the strength was), and currently trying LA-200 - gave her an injection of .4ml and she will get another tonight or tomorrow. Should do tonight - day 3. it "might" be helping but it's almost hard to say. So I ordered the gallimycin because it's said to treat coryza. Not culling at this point. I've read up on CRD, MS and nothing seems to fit. She breathes through her mouth and her eyes/nose have discharge. Otherwise, she's ok. however, I'm not sure how she is seeing. I throw scratch and she hears it and gets excited but doesn't seem to be able to find it. She eats out of her bowl in the house and drinks from her waterer. Kind of strange. Maybe she just can't see as well as she should with the swollen sinuses. I clean her up at least 2x a day. Poor girl, she's been through too much cleaning and too many shots! She's a 2# silkie. thanks for any advice. I did message Peter Brown and he thought it might be canker but I don't think so per pics I've looked at, it's not the same at all.
