Well, I'm with Bay on this....and I DO HAVE some fields with the one FEM suggests &both types are the Red Brand. IF YOU PUT ELECTRIC inside, it makes the field fence last much longer. The minis loved the rub their winter haired butts on it! It WILL STRETCH...the goats like to just lean into it from shoulder to butt and walk along to scratch of winter hair. Then, the spaces become distorted. Both are good fence but, without the electric you have to watch your animals habits. With goats, if they decide to use it as a ladder to reach tree limbs, vines, etc., it will push down. With either, installation is critical to keep tight and not allow for the pull down, where it kinda folds up at the bottom. I have some wood & some T-posts interspersed to help keep the fence UP....the hooks on T-posts CAN pull down over time. Yep, some of it is 15-20 years old now!
