Height a Wyandotte actually needs
A Wyandotte chicken is one of the heavier dual-purpose breeds, with a broad body and short wings that make sustained flight unlikely, but a startled Wyandotte can still flutter and scramble over a fence that is only three or four feet high. Five to six feet of side fencing contains this breed comfortably in an open run. Where planning, trees, or a small garden make that height awkward, a four-foot fence can work if the run is fully covered with netting or a solid roof so the upward escape route is closed.
Height alone does nothing if the top edge is inviting. A flat top rail gives a Wyandotte a landing perch from which she can simply drop down the other side, so angle the top outward, use a loose netting overhang, or run the mesh up without a perchable ledge. Hens that learn one successful hop will repeat it daily, usually at the same low corner or beside a coop roof that acts as a stepping stone, so move objects away from the fence line inside the run.
Mesh that keeps hens in and predators out
For a Wyandotte run, welded hardware cloth is the right material and hexagonal chicken wire is not, even though the names suggest otherwise. Chicken wire was designed to restrain poultry, not to exclude foxes, dogs, or raccoons, and it tears and rusts quickly at ground level. Hardware cloth with a small square mesh keeps a Wyandotte's head from poking through to graze outside, stops reaching paws, and stands up to hens scratching litter against its base.
Fasten the mesh to the inside of sturdy posts, overlap joins so no gap opens, and check corners where two runs meet because that is where a hen can squeeze through a triangular opening. Bury the bottom edge or bend it outward into a flat apron pinned along the ground and covered with soil or slabs, so a digging predator meets mesh wherever it starts. A Wyandotte herself will not dig out, but the hole something else digs in becomes her way out.
Gates, pop holes, and daily weak points
The pop hole between coop and run, a garden gate opened while carrying feed, and a dust-bathing dip scraped under a panel are where Wyandotte chickens most often leave a run that looks secure on paper. Fit gates with latches that close under their own weight, keep the threshold strip in place so litter cannot build a ramp over it, and fill any scrape that deepens along the fence line before it becomes a crawl-under gap for a smaller hen or pullet sharing the run.
Inspect the Wyandotte run at bird level, crouched down, once in a while. From standing height a fence can look perfect while at hen height there is a lifted mesh corner behind the feeder, a gap where a post has rotted, or a stack of logs offering a staircase to the top. Young Wyandottes are lighter and more athletic than mature hens, so a mixed-age flock needs the fence judged by its youngest, flightiest member rather than its calmest old hen.
Containment that fits how Wyandottes live
A Wyandotte chicken that has enough room, forage, shade, and dust-bathing space inside her run tests the fence far less than a bored hen in a bare pen. Scatter scratch feed away from the boundaries, rotate the run or rest sections of ground, and give perches and shelters in the middle of the space so the flock's daily activity centres there rather than along the wire. Containment works best when the inside is simply more interesting than the outside.
Even a well-fenced flock can lose a bird through a gate left ajar during cleaning, so a quick local alert matters when minutes count, and KinsLe's Lost Pet Alert System covers that moment by notifying nearby members while whoever finds your Wyandotte can message you directly.
