Im looking to have a few chickens (and my fiance wants a duck) , would love to this spring. Right now i have an empty horse barn with 12x 12 stalls tht i was hoping to comvert to a coop. I was going to seal it off from predators and habe them locked in at night so they stay safe. However, how am i to keep them from just taking over the whole barn that i cant effectively seal up from predators. Im not wanting to build a run as i already have too much to mow and weedeat around as is .im in indiana, so main predators would be dogs, hawks, coyotes, raccoons, possible a mink. What would you (experts) do? Thank you!!
