I live in Portland, Maine and own 3 silkie hens. They have lived inside for a year and I'm looking to move them outside now that its spring. I bought a nice secure coop and run from ebay and I'm wondering what I need to do to prevent borrowing animals from getting in. I read somewhere that I should dig about a foot into the ground and put wire under. but might placing large logs around the run work too. because in Maine digging is really hard.
