I have electric poultry netting that I typically use for my birds... mostly to keep predators out. The netting is the typical 4x4" and doesn't hold in little chicks. So now I've got momma and little ones who want to hang out with the big guys, so here are the problems: - the fence doesn't hold in the little guys, but they generally stay with momma who can't get out - And I've been keeping the electricity off cause the little ones are only a few weeks old. Do you keep your electric fence on even with little chicks? It's a big jolt and I'm afraid they could really be hurt since their bodies aren't feathered out yet. At what age is it safe to turn the fence on?
