Second coon question of the day. I have a Catwaba chicken ark, like these: http://catawbacoops.com/the-catawba-converticoop-chicken-coop-image-gallery.html It has a ramp which gets pulled up at night, sealing the chickens in very well. We of course do this every night and open it up every morning. We will be gone for one night this weekend. I have someone coming during the day to feed and water the chickens, but do not want to ask her to get up at the crack of dawn to lower the ramp so the girls can get out of their small enclosed roost area. It may be hot and it could be dangerous to leave them there till a reasonable hour. Our plan was to leave the ramp down while we're gone and to move the ark onto a large concrete patio and also wedge it in with cinder blocks. The thing is HEAVY--a raccoon will not be able to push it off the patio. That way no one can dig in/under and get them. But can a coon chew its way in through the field fence? It is very well secured--I seriously doubt it could be pried.
