I am not Leahs Mom but she convinced me last year to get electro netting

I purchased mine from Premier:
http://www.premier1supplies.com/c/fencing/electric_netting/ & I love it. It keeps my dogs & other predators out but the girls in. I am contemplating getting a 3rd roll. But 2 rolls give them an enormous area to range in. You just need to move it when the grass gets tall. I am able to set it up, move it & take it down on my own. Mine does not have a solar charger but its on my wish list for next year.
ETA oops sorry didn't see LM's post
ETA#2 the fencing should last for many years so its a one time price that you benefit for many many years to come. Its a good investment in my opinion for those who can not allow theirs to free range wherever they want yet it allows the chickens to be out in your yard eating whatever they find & cutting down on your feed bill. My netting takes up a 1/3 of my acre yard and they find plenty to eat allowing me to cut their feed to a 1/3 of what they normally eat. They each get a 1/2 cup of food per bird and once they are out in their netting I only feed at night. They have to find the rest of their own food all day
