We have been feeding our chickens Countryside Organics since we got them - 2-3 days old, and recently switched to grower feed. In the grower feed, there are small peas and none of the chickens will eat them. They can't be too large; I've seen them eat seeds and chunks of food that that are larger than the small green peas. I hate raking all the peas up that they toss as they eat. Plus, I wonder what they might be missing nutritionally without the peas. (I should add that all of them look very healthy and big for 13 weeks. Is there a better way to handle this? Should I go back to starter until they get layer?
