I have 29 chickens on my property, plus 4 turkeys in 4 separate coops. All the laying hens are let out to free range several times a week. Yesterday, I noticed one of my laying hens has what appears to be scaly leg mites. I have researched this site and a few others and decided to treat all the chickens and turkeys as follows: rub canola oil on all their legs (I had just gotten a gallon from BJ's, so I had plenty), plus remove all bedding and dust down the coops, roosts, and chickens with Sevin dust. I am concerned that we will be unable to continue treating their legs for the recommended week as I am due to have a baby on Wednesday. Will it be enough that they had some oil treatments, plus the dust? Do we have to re-strip the coops and re-powder everything in a week to ten days? Is their something else I should try since we will be unable to continue the oil rub throughout the recommended time period? Thank you in advance for any advice.
