I inherited some chickens from granddaughters project. I feed them scratch mixed with layena and oyster shell but read that scratch is insufficient to fee my chickens. I have 5,a rooster and 4 hens all approximately 1 1/2 years old. We have 3 acres and they pretty well free range but want to know what kind of feed to feed them. I am 78 and still garden some so they really enjoyed my tomato plants. I used to do rescues taking in and fostering dogs and cats but it got too much as I am "getting" older. Still have 3 dogs and multiple cats that call this place home. They as well as the chickens all get along really well especially since the 4 legged one fear the fly swatter. Any help you can give me on the correct feed would be appreciated. They were laying eggs regularly until this last cold snap.
