It's tough to make a chicken tractor light enough to pull and still strong enough to keep out predators.
The photo above shows how Kayla used movable screens to keep a hawk
from reaching through the mesh into her chicken tractor.
We recommend not trying to beef up your tractor to keep out raccoons. Instead, keep your chicken tractor very close to home (and get a good dog, if possible) to scare any potential predators away.
With raccoons, it's also handy
to make sure your birds eat any kitchen scraps very quickly. We
learned the hard way that raccoons will come for scraps and stay to eat
your chickens. Better a flock that only eats store-bought feed and
grass than birds with a more diverse diet who end up in a raccoon's
belly.
Hmmmm Coon Hound ,any large terrior type dog (try the local pound ) ,.22 rifle / 410 loaded with buckshot .
We've had issues with raccoon predation before. It is not fun. They always seems to be interested in the younger birds. Not super little (since you'll be watching them close in the brooder) and not too big, but usually right at the point where it will cost you the most time, feed, and emotion. At least in my experience.
We moved even further into the woods last year, and while I second the opinion that a decent sized dog or two is a must there are some easy, cheap structures that may work better for you. Bot can be seen here: http://www.therewasafarmerhadablog.com/2014/08/pppp-report-week-8.html
"The Box" is 2 hog panels with a bit of cheap plastic mesh. An additional hog or goat panel roof could be clipped on at night for 100% locked down protection.
The third photo on that post is a new structure. 2 cattle panels arched over a 8x10 frame. When the young birds move on to the main coop or freezer I think it will get a clear skin and be a mobile greenhouse.
I would be happy to respond to comments on the blog (or emails) with questions about what we're doing here or how to build these things if you need, or if there's something I didn't explain well enough here.
