I ordered some ivermectin to treat the mites I have living in my coop and on my chickens. The delivery could not be made on time due to crappy weather conditions so I went ahead and dusted them all with DE yesterday. I also dusted there coop with wood ash and DE. I got the Ivermectin in the mail today.... So my question is can I treat with ivermectin today even though I just dusted them all with de yesterday? the mites are still on my birds. One of them can not open their eyes because the mites are so bad. I gave him a bath two days ago using Dawn dish soap, and flushed his eyes out with diluted boric acid and applied Neosporin to his eyes. I also dusted him yesterday. And his eyes are stuck shut again today, and covered in mites. :/
