After reading the sad story of a duck killed by an animal, I am scared to let my babies outside when they grow up! I live in the country (north MN) and we have all sorts of critters out here. Foxes, wolves, muskrats, mink, bears, skunks, possoms, you name it. I have a small grain house (about 300sqft) we are turning into a bird coop for the guinneas and the ducks, but will the critters beable to get in there and eat them? It has a couple holes we will parch, but it is sturdy with a sliding wood door. I told my husband, maybe put the ducks in a dog kennel inside the bird house for extra protection (Guinneas can at least fly onto rafters if something bugs them). But what about day time when they are out side exploring? any ideas? I really cant afford to build a huge pen for them.
