Well, actually, they will eat sunflower seeds and treats, but they don't seem to be eating their feed. They are drinking tons of water. I just saw the other post on Purina Layena; could it be that their food is moldy or something? It's from a new bag. I didn't fill their feeder and so I didn't see the condition of the feed bag - it's all been emptied into a big feed bin. It looks OK to me, but I may not be able to tell from just looking. Should I go buy another bag? Will chickens not eat feed that's gone bad? Or is it more likely illness? They are acting fine otherwise, although not laying quite as many eggs as usual. They are about 7 months old, if that makes a difference.
