My chickens have a pretty bad mite infestation again..... my neighbor doesn't have a door on his garage and asked me to keep them indoors from now on ...... I have just dusted them all with permethrin, but it sounds to me like ivermectin is the quickest, easiest, and most effective method. If I go out and get Ivermectin this afternoon, should I wait to apply it, or could I apply it later on today? Also, any suggestions on letting my chickens out and keeping peace with my neighbor would be greatly appreciated. I was thinking about asking him if he would mind stretching 18" high poultry netting across the front of his garage till he gets a door......who builds a garage w/o a door???
