I feed my girls all our veggie scraps I also make them whole wheat fodder and I have a tray of oyster shell available at all times plus they have free range of field and wooded area I also throw scratch daily as a treat (mostly in the evenings to warm em up) I'm considering adding BOSS maybe even sprouting it first. Do I also need to be free feeding layers feed? I don't want them to be obese. I have such an array of hens (different sizes)it's hard to put out a specific poundage of feed a day going off of weight and I don't even know what that should be anyway. If I did do layer ration I think I will do the FF how much should be taken out daily per hen? Can I do FF and fodder?
