My poor girl had lice and a respiratory infection. After two Dustin's with ProZap, all bugs, nits, and eggs are gone, feathers are coming back. For the infection, she had foamy eyes, that awful smell, and coughing. Gave her Duramycin in her water, then Corid, and finally stumbled upon the potential for a coryza infection so she has had 2 doses of Tylan 200 (1 10 days ago, 1 2 days ago). All symptoms have cleared up except these sinuses. She is eating and drinking again as well. Any other ideas?
