Ok so I found food grade DE and I admit the stuff seems to work great BUT I still keep getting buggies on the birds. Ok so first my polishes got infested with lice. No clue how. No one else showed any signs but out came the de and the 7 dust. The regular dust bath spots got a good dose of DE. Can I do the same with 7? Anywho the offending birdies also got a good dusting with 7. They were separate from the others so I thought that would be fine. Now my baby birds who are still caged but the cage is inside the coop have Mites. Losing my mind. Ok so today I gave them a good DE bath. I will check them over tomorrow and probably dust a bit of 7 on them. I cannot see how this is not affecting the other birds. They must have them too I just am not seeing them yet. So obviously the DE I am using so liberally is not doing enough. So what do I do now. I hate to catch them all. Its such a stressful thing for them and in this heat.... well its just stressful. Can I add 7 dust to their dust bathing spots? will this help or hurt? Or do I bite the bullet and pull in the family to start a production line to treat all the birdies? Also how is this happening. No new birds have been brought in. The last girls have been in with the others just 3 weeks but I had them for 21 days before I let them join the flock and I checked them regularly. I will win this battle over the bugs somehow. So any other advise would be appreciated.
