I bought a straight run of BOs. We will keep some of the ladies (aprox 12) for layers and a roo but the rest are going to be processed. There are 8 weeks old. they are all intermixed and have been eating the medicated baby mash. Is it time to switch to something else? Should I be using a grower ration? I am in need of getting them more food soon so I would like an answer soon so I can hike out to the store to get the most suitable food for them. Thank you for any and all advice.
