I have 6 chicks who are about 7 weeks old and they have been out in the coop isloated for a couple of weeks. We also have them their own pop door and run, however, it is contained inside the big girls pen. Anyway, we have been letting a big girl in with the babies one at a time and checking out how they behave. So far, so good. Now when we can fully incorporate both flocks together how in the world can we make sure the babies eat the right food and the big girls eat theirs? Any suggestions. What will happen if the babies eat layer feed and the big girls eat the medicated grower food? Any ideas?
