Hi, My girls are free rangers in a great area of our property. The issue of late is that our oldest about 2 years and the young'ns, 9 weeks are hopping the fence. It is short so I guess it is amazing they haven't until now. They seem to be coming to greet, who ever has just arrived home. I'm sure for the expected treat. However who knows how many times they are out during the day while we are not home. We have some dog issues from time to time so is there any suggestions on how to make a short fence taller with out a lot of expense. Is there such a thing like chicken hot wire fence. Thank you for any suggestions.
