I keep getting some conflicting info about calcium. From what I have read, if the hen is fed a well balanced diet and a good feed...she wont need the calcium. I feed flock raiser and they get garden scraps daily (greens, greenbeans, tomatoes, corn, peas and more). I have one BSL who's laid a perfect hard shelled (double yolk!) egg for 8 days. Do I still need to offer them calcium on the side?
