What do you feed when you have different age chickens and they are all together? I have 3 months to age 3. I have tried to separate them and it isn't working. They all like to be together. My question is I need 3 different feeds for the ages. how in the world do I do this or is it ok that they all eat the same feed and if so what kind? My 3 month olds don't need Layer feed my 6 months need growth feed and my 4 months need chick feed. Please help. Im worried each age won't get the nutrients they need.
