Any suggestions? So far i have: corn, green beans, kale, sald bowl mix lettuce, swiss chard, a few differant types of hot peppers, radishes (can they eat radish greens?), broccoli. What else is good for them to eat?
This chart is a standard. Pay attention to the "do not feeds" at the bottom. As it says in the bottom, if you do feed the "do not feeds", do not expect them to fall over dead the next day. Most cause long term damage to internal organs, so just because somebody fed them and their chickens did not immediately die does not mean they are not being harmed.
I don't know specifically about radishes.
If you are planting something specific for your chickens, I'd suggest greens, things like lettuce, kale, chard, spinach, mustard. These can produce a lot of food in a small space with limited effort on your part and they don't care if they bolt or go bitter in the heat.
