These are my sweet babies. Thank you Dale Anne. They seem to have attached to hubby and me, and they cry when we walk away from the pen. I am hoping they will grow out of it and realize that we do always come back. A few times they have gotten out and followed us, but will go back into their pen. We currently have field fencing with chicken wire and hardware cloth wired to it. We also have a strand of electric fencing around the bottom inside. The electric wire seems to not bother them at all. We even took the charger off the pig pen and tried it on theirs. The tester says that it is working. They act like it it a private step to use to climb the fence. Anyone have any experience with something like this?
