So I can switch to the all flock in a few weeks and be okay ?
Whatever feed you decide to buy.... CHECK THE MILL DATE before you drive away with it.
The date the bag was milled is printed on the white part that makes up the seam at the bottom of the bag.
The closer to today's date, the better, especially if you only have 2 chickens and it's a long drive for chicken food. Don't be afraid to ask them to look for newer bags!!!!!!!!!!
