We live near a creek, and the creek is normally bone dry. But we've gotten so much rain this spring that there's a lot of water, pretty much standing in the creek (i know that doesn't sound right, but it's true).....and thus we have an alarming mosquito population right now. Should i be concerned about my chickens? If yes, is there something natural i can do to protect them? I appreciate any advice you can share. Thank you!
