Hi! We have a backyard free-ranging flock of 15 and have had birds now for 3 years. We started with the girls as tick control and yummy eggs and now are moving onto meat birds. We like the idea of day ranging our meat birds but are curious as to if we really need the electric netting for them? This may sound dumb, but is it more for the keeping the chicken in one area, or keeping predators out? We are planning on closing them into a portable coop at night and letting them out in the penned area during the day and moving the area every week or so for fresh grass and bugs. I am looking for advice on whether the electric netting is necessary or if we can get away with non-electric just as easily. We are planning on keeping the birds 16 weeks or so, then off to freezer camp. Any advice would be greatly appreciated! ThankS!!
