I sprayed all of our adult birds, the pens, and the coops with Permethrin 10 yesterday to keep away lice and mites that the squirrels always spread to my chickens. I want to know, is it okay to put my 7 baby chicks that range from 1 week old to 2 weeks outside in their pen after I sprayed it yesterday? Will the Permethrin 10 hurt them? They are little bantams. If it's not okay I can just keep them in their indoor pens but it's a nice day and they prefer being outside. Thanks in advance for any advice.
