via http://ift.tt/1TctWRA:Farm Fresh? Natural? Eggs Not Always What They're Cracked Up To Be:
In case you were curious, as I was. I often see “Vegetarian-Fed” and wonder WTF? Chickens are not naturally vegetarian.
The short answer: most of the stuff on egg cartons is legally meaningless. The rest is misleading at best.

Dogs are carnivores, but you can feed a dog a food that's built of corn gluten and soy, and it'll be fine (maybe not AS perfectly healthy as one fed an animal-protein-based food, but in the "statistical averages" way, not the "go to the vet right now" way). Cats, however, are obligate carnivores, and a cat food made only of plant proteins would kill them. (At least without supplemental taurine. And I don't know where the percentage cutoff might be - would they be okay with 50:50 plant:animal protein sources? 80:20? 95:5?)

Date: 2016-05-01 11:48 am (UTC)My sister's farm switched to organic feed recently, and their feed is made up of corn, oats, and soy, and they use the same feed for meat and egg chickens, and their pork. All the livestock get the same, thing, and in the summer it's no big deal because they can get whatever else they need from the pastures they're kept on. Over the winter, my brother-in-law did a bunch of reading and started supplementing the egg hens' feed with-- mostly calcium, actually, and suddenly their egg production doubled at midwinter, and he realized they weren't getting what they needed. In winter they're shut in a greenhouse, so they really don't have any forage; they go out during the day, but since the greenhouse can't move, the electric perimeter fence can only be moved so far, and they don't get fresh pasture-- besides which, the pasture's not up to much, it being winter.
(There are no meat chickens on the farm in winter; they don't breed them there, so they can just buy new chicks in early spring.)
So, chickens are certainly not obligate carnivores. But some backyard flock enthusiasts will go to pet stores and buy their little flocks mealworms and the like as supplements, because they really don't thrive on a vegetarian diet.
