oh my. mites. help please. so many questions*...i've just noticed one of my girls balding and acting strangely, so it must be mites. i am going to submerge her in warm salt water as soon as it warms up outside, bc she also has a poopy bottom. salt will kill baddies, (got rid of flystrike that way.) *i haven't seen where anyone has just used salt and wondering why? *my coop is an old large shed with deep litter and stacks of straw bales. can i just treat/spray/powder my entire coop area w/o removing everything? is all my straw ruined? raking out and removing straw and bedding would take FOREVER. please, if anyone has had success doing this please speak up! *i have 5% sevin, can i just dust EVERYTHING with that? i have DE that i put on the coop bedding last night. *has anyone had success using the 2c. water/1 c. cooking oil/1 T. dishwashing liquid to spray on the hens and in the coop? *i'm looking for permethrin on amazon. what kind do i buy? there seem to be different %'s. this is just so daunting. and i am so worried. (apologies for the duplicate post, not sure where to post to get the quickest answer.) thank you so much for your help.
