About a month ago after one of my hens fell ill I discovered a mite issue we acquired after purchasing some new hens at a local swap meet. I immediately dusted the coop with DE and sprayed the coop and chickens with poultry protector. I repeated the poultry protector once more and have dusted with DE weekly. This morning I found some more mites on the hen with the original issue. After doing some research it seems like DE isn't the most effective treatment. After researching some alternative products I'm interested in Prozap poultry dust and Scalex mite and lice spray for birds. My questions are: A) Does anyone have any opinions on Scalex vs. Poultry Protector? And B) Will there be any egg withdrawal period with any of these products?
