still trying to get a handle on feeding as new chicken parents...what is the difference between pellets and mash? We have been giving the chickens mash since we brought them home 2+ weeks ago. Then I am reading about pellets, so I am not sure which is the preferred feed. The food lists it as good for layers, but still no eggs ( we think they are only 3 + months old, so maybe not yet). Just trying to do the right thing!
