I have 11 leghorns in my flock, and I am impressed with their foraging skills. I wouldn't have expected that from a production breed, but there you go.
I have a couple of polish hens too, and those goofy looking little things have a lot of "chicken" in them too...very good foragers.
Good questions, @AccidentalFarm - I fear I’m still in the early Googling phases myself, so not real clear on advantages of the varieties. Please share any tidbits you uncover, and I’ll do the same.
My chicken area backs up to woods, with a fence keeping the flock out of the woods. I was...
Ha ha...you'll want to reconsider that...under those leaves are plenty of manure, rotting food waste, old bedding, etc. :lau
Doesn't stop by 4-year old daughter, though...
The temps up here in RI warmed up into the mid-40's today, so my flock got a delivery of about 12-15 barrels of leaves raked up from the neighbors yard. There's enough little bits of grass, weeds, and who-knows-what in there to keep them busy scratching and snacking for hours!
The “other livestock in outbuildings” part is probably key to increasing winter forage in cold weather. The chickens will pick and scratch through bedding/manure, clean up any spilled seed, etc.
Yes, up here it’s really more about “supplement” than full-on “independent living”. In the warm weather I see a 50% reduction in commercial feed reduction, maybe more.
But winter is tough. Warmed up here today so the snow melted, allowing for a bit more snacking on compost pile.
I’d expect in northern climates, you’d need to supplement in winter...either with some combination of fodder, grown grains (corn, wheat, etc), finely cut hay, long-storage veggies like pumpkin and squash, compost piles, food waste, or chicken feed.
