Corn as feed.
I don't eat mammals that are fed corn to fatten them and try not to give much to my chickens. I suspect organic corn may be OK, but not the industrially grown product. In addition, those commercial animal meals are very processed.
I hardly compost anything from the kitchen or dining room: I give it to them. Today they are getting our left over Greek pizza and a little organic ground pork: $2.59 from our food coop. I bought a bale of hay/straw--whichever one has the seeds. It gives them a great alternative to the 15" of snow and ice on the ground here, plus something unprocessed to munch on. Tomorrow they will get the shells from our shrimp dinner. We give them any veggies or greens that we don't eat.
There is a lot of food that is just wasted that could be fed to our chickens. Let's feed ourselves right and give the leftovers to them.
Awaiting the next blizzard in NH.
