We've provided our three hens with a well ventilated coop and a secure 44 sq. ft. run. We like to let them out into a fenced 'chicken yard' when we're home and vigilant (or at least when our golden retriever is out in the yard, being vigilant). Trouble is, it seems that two of our hens aren't satisfied with the ~400 sq. ft. 'chicken yard'. Our California White and Barred Rock like to get out of the 'chicken yard' and forage around the rest of the back yard. This isn't a huge deal during the late fall/winter months, except for the mess they make scratching around in our flower gardens and scattering mulch in the grass.
So, I'm hoping to try and keep them in the 'chicken yard' without covering the whole thing - this is expecially crucial this time of year, with flowers and things beginning to sprout and really critical once we get our veggie garden in the ground...
My initial idea is to install some sort of 'whiskers' along the top of the 4' gate they hop up on. By 'whiskers' I mean those things that are used to discourage pigeons from roosting/nesting on building ledges. Has anyone tried those to discourage chickens?
I'm going to start with the easiest/cheapest option and slowing escalate my efforts until I find someting that works. I'd love to hear about anyone elses experience with trying to contain wayward birds within a 4' fence...
