So I am inhertiting a rooster from my mom sometime in the next few weeks. It's whole life it has been fed layer feed (they didn't start with chick feed or even grower feed, just straight to layer, don't ask me why I don't know.) I know of plenty of people that feed their full grown roos a layer feed diet, but he is still only 2.5 months old. Is there any sort of health problems I should prepare myself for due to bad diet? If so, any ideas on how to get the boy back on track? Right now he seems small for his age, smaller than my girls anyways. My girls are all right around the same age and they're all still on grower feed, is it okay to switch him straight from layer to grower or should I mix for a while? I want to make sure he is healthy and happy, but I am concerned about the diet he has been fed so far. No greens, fruits or veggies at all... just layer feed since they got him at about 3 weeks old.
