We have discovered a fairly big mite infestation in our coop (and on flock). We live in the Pacific NW. Today will be unusually not (over 100 degrees!) I have to work the rest of the week and really need to treat the coop and hens/roos but am worried about over stressing them. Is it a bad idea to treat them today? I'll be using Elector PSP...not cheap but supposed to be effective!
