local feed-store lady told me all lettuce must be chopped up to prevent crop problems - is this true? I've been giving my girls mixed spring greens (like mesclun) for the last few days but I was just giving them essentially a big bowl of salad. I don't want to make them sick! They do have grit and are outside with lots of dirt to peck around in. The only other thing they're eating is grower crumbles, and I treat them with oatmeal and yogurt in the morning.
