I have just started my eight week old chicks on poly-tonine A complex. They are housed but seperate from my layers. Should I put this in the hens water as well? If so can we continue to eat their eggs while their on it? Everything I have read says it is only vitamins, but then someone mentioned it has antibiotics in it. I should mention I am allergic to penecilin and so is my four-year old son. Thanks!!
