I have a yearling peacock (Wolfgang) who has developed a mite problem on his neck. I have sprayed him several times with Manna Poultry Protector with no improvement. Catching him for spraying has been very stressful for him...and for me. Is there something I can put in his water that will help get rid of the mites? I read that Ivermectin for horses, 1% injectible can be used orally. Does that mean I can put it in his water? If so at what dosage? I am a bit nervous about this since I have had no experience with Ivermectin. Any suggestions?
