Folks, I very much appreciate the advice and guidance. This is my first experience with any type of malady or otherwise negative situation and, given complete ignorance, has been stressful.
My photographer friend will return this weekend and I am hoping will help with the 1st treatment. She has a phobia to bugglies so I will be holding, she will be spraying. I will do the process at night in the garage and birds will go into a cage (8' by 4' by 6') overnight. Once completed the birds I will liberally spray the coop. We are currently below freezing here at night so an added complication.
Starting next Wednesday we are to have a week of 10C and above weather, I will complete my extended covered 12' by 12' run then empty the coop of bedding, re-spray and then replace with new bedding (pine shavings and straw). This project has been on the books for a year so the motivation to get it done is welcomed and will make winter life for the birds much more pleasant,
I will post pictures as I progress,
