My two drakes have what appears to be fleas around their eyes. I have DE'd and lymed the dirt in their run. I have also bleached all of their house and toys, feeders and waterers. I have been putting Vaseline around their eyes and face two times a day to try and smother the fleas but it doesn't appear to be working. I have even dusted the birds with DE a couple of times a day as well. Nothing I have been trying seems to be helping them. In fact they seem to be getting worse. What else can I try to help with my babies? Are these even fleas or are they a type of mite? Where would they get anything like this and what can I do to prevent this from happening again? Never had to deal with anything like this before.
