Thanks everyone for all the responses. The pigs are in the corner of the pen but the lighting isn't good. One is a yorkshire and one is a hampshire/duroc cross. I dug the fence down almost a foot and filled it back in on the inside and so far it is working well, but I am watching very carefully for signs of escape attempts. I will be posting a lot more pics of my chickens soon because I am getting a bunch from different sources in May.
Thanks again everyone- I'll post more as projects are completed.
