Any chance that guineas can be trained to let themselves in and out of the coop via a 6 foot high entrance cut out of the side of a loafing shed? The open side is protected with wire fence, and I would attach a little landing area/shelf for them to get in and out. I would also shut it at night. Or would they be too interested in trying to get in through the fencing at ground level? They are about 3 months old and have been penned outside (in the loafing shed/coop) for the last 8 weeks. Thanks.
