My daughter's have taken up chickens and I found some natural pesticides using herbs for the chicken's i.e. spraying Neems oil in the coops to rid of mites etc. - I have taken up the waddlers...am wondering if there are natural deterents to protect the ducks from bugs too. Also, live in Minnesota and am wanting to prepare for winter am wondering about enclosures - what type of bedding to use, how often to clean out cage and how to keep ducks mite free etc. - Would love your in put.
