Hello - I'm a complete beginner and would be grateful for advice on a couple of things. I've wanted chickens all my life and excited that I'm at last in a position to own 3 or 4. The area I'm planning on using is 9' x 35' surrounded on 3 sides by the house wall and garden walls which are approx five and a half feet high. The ground has a paved path with the rest mostly covered with red chips. I am wondering if I should replace the chips with bark or would the hens prefer bare earth? One wall is heavily covered with ivy which I think the hens might be happy to wander and shelter under. On the other side of the wall is hotel grounds with fairly dense shrubbery, felled branches etc - an ideal climbing opportunity for a fox! Would topping the wall with electric wire/rope/tape be successful in keeping Mr Fox out or would the ivy etc cause a problem with the workings of the wire?
