I know when my chickens have lice or mites because I feel them. I have to run in my house and wash all my clothes and shower. I feel them on my head and face, awful! What I do is put the dust in sock and hang it over the door so every chicken gets a little dust. I think it is much better...
I have 10 hens and a rooster for pets and eggs. they are in a sealed enclosure. I want wild birds to live on my property and rid me fo fleas and ticks. I will provide food and water. How about Guines birds?
