I am at my WITS END with the d&%$n deer here. We have 7 acres with multiple turnouts. Front turnout is DONE with post and board on front and 5 strand of spur poly covered high tensil on back. WITH a top and bottom electric line. NO issues here it is about 3/4 of an acre. No grass with a downward slant. We put 2 round bales in it and the 3 horses eat the 2 roundbales in about 12/14 days. Obviously not enough room and no grass. 2 years ago we finished right down to the big cattle gates front and back. totally done. In the back. we have the front of the back done with the wooden posts as in the front pasture. 3 strands of electrifies high tensil no issues there. But the back of my 2 back pastures backs up to a small mountain and stream. In years past with different horses I had one in each of the pastures with NOOO issues ever. In the last 2 fricken years, the $%^&#^ deer will tear down the back line that is at the bottom of the mountain. From there they go to wherever, but if I have horses in the back about every 3 flippin days the deer pull down the line , i don't know and then I get neighbors, or animal control at my doorstep and I have to round up horses , put them ALL in front pasture and fix fence. Dh hasn't griped yet. They stay in front till he fixes it then I try again. Well I give up!! FOr now. The back line is METAL t posts, with electrified high tinsel at about 3.5 to 4 ft. The deer come down and just pull my line off the t posts. I can't figure out why I didn;t have an issue until the last 2 years, maybe a huge uptick in deer??? IDK , I also have neighbors who feed the deer corn! ANyway call me heartless but I am SOO over the whole bambi thing! So Dh proposes another barbed wire fence 5 ft in back of my horse fence that he thinks MAY stop them. He DOES worry about the possibility of horses getting TO the barbed wire ,but again it would be a second fence on the other side of the horse fence. Another horse friend says he would hunt them this year for us and take his entire allotment (6) from out property. I DOUBT this will make a difference. Someone else said my dh should mark the back line regularly with his own urine, OR use deer blood and moth balls on a regular basis. As this is a very cheep way of fixing problem I am willing to try but doesn;t seem like it would work. Long term I am thinking wooden posts along back and five lines of the spur poly at 1 ft intervals. I do wonder if that would work, maybe they would stretch the poly, maybe break a post? IDK. NO ONE seems to have a good clear way to fix this but I am soo tired of not being able to use thee magority of my turnout. ANYONE have expereince with deer/fencing and horses?
