I understand what your saying. But with so many other greens/things to feed, I just wouldn't think it would be a problem. Kinda forgetting too, living in a big city, there are tons of things available here that might not be in smaller cities.This is a good point, Barb. But for those of us feeding many animals, a couple heads of romaine a day added into the many other things in the tub, is sorely missed.
