Is there any way to keep carpenter bees away from the chicken coop? I don't want them chewing a way or building a nest in the wood. Also, I have ants crawling up the side of the coop carrying eggs.. any way to keep those away other than chemicals that may harm my chickens? And one more question.. my neighbors yard is home to a family of crows.. I have 3 full grown chickens so I'm not very concerned, but I've heard crows will gang up to kill a chicken. I've seen them chase away hawks though, and we rarely see hawks around because of them. Just post thoughts on if I should encourage the crows to stick around or not.. thanks!!
