My husband, myself and three kids have 8 chickens. Three Bard Rock, two Rhode Island Red and three white leghorn. They will be 3 months old on the 27th of July. We are now feeding them "Grower" since they have completed the medicated "baby chicken" food. This was at the instruction of the local Agway. When do we switch to "layer" food? Please excuse my ignorance....we are trying to learn as we go. We are all having a wonderful time with our new "pets" but since we are SO new, I feel a little embarrassed at the lack of knowledge. I am depending on this awesome website to really help us!
