But, I was wondering, what do you do if for some reason you cannot obtain or cannot afford chicken feed? My chicks do free range but I don't think they could survive doing that. Suggestions? Would you stockpile their feed just as you would food for yourself? Thanks!
Processed chicken feed is good for a couple of months, then it starts to degrade. I would not advise stockpiling hundreds of pounds of chicken feed over a long period of time.
Oats - oats stored in mylar bags with oxygen absorbers can stay viable for close to 20 years, if stored properly.
Corn - dried corn stored in mylar bags can be ground and fed to chickens.
Worms - worms from compost bins.
Table scraps - as long as the scraps do not contain anything that will harm the chickens.
Foraging - given enough land, and variety of greenery, chickens can do well.
The problem with foraging is that during the winter months bugs for protein will probably be scarce. And, if you live in a northern state at gets a lot of snow, the ground will be covered.
If you live in a southern state that does not get any snow, then the chickens should be able to forage.
Keep in mind chickens come from a wild jungle fowl. Chickens love to dig around in leaves, around trees, through the grass.
When I let my chickens free range, they will eat the leaves off the weeds until the weds die. They eat just about anything and everything.
