One of my 12 chickens has mites and I usually use Elector PSP to treat them but since it's winter I used Permethrin powder and dusted all of my chickens yesterday. I also cleaned and dusted the coop and run. It's going to be near 40 degrees today and I'm wondering if I should spray the infected chicken with Elector PSP today as well. I'm unsure if the two products can be used together and also if 40 degrees is still too cold outside to spray the chicken's feathers (it will be near 30 degrees overnight tonight). I do not have a heated garage or basement where I can put the chicken while her feathers dry. This is my first time using Permethrin powder and the application instructions state I will need to repeat dusting the chickens and the coop/run again in a week. Any thoughts or recommendations are greatly appreciated! Thank you!
