Hi! We are soon to be refencing some areas on our property. We were thinking of using 2 rail pine post and rail (copper logs). Any tips on things such as post and rail length, height, depth into ground, diameter, best way to secure the post and rails etc would be appreciated. Also hoping to blacken the logs afterward, is there anything i can use that will discourage the horses eating the fence but won't hurt them if they do, preferably something I can spray on rather than something like painting on the usual sump oil? Thanks in advance.
