Quote: I have never fed scratch grains in 35 years. I do not know your set up or your goals as a chicken person. Some feed scratch grains exclusively. If you plan to have chickens for two laying seasons and butcher them out and replace, they will be OK I think. I am not positive. I do know scratch grains is not for birds that you plan to have for 3-6 years.
Instead of scratch grins, try a head of cabbage and a pumpkin one a month. Toss in some cucumbers, beets and a few heads of garlic the next month. Those things are better, will keep them busy and entertained and best yet if you grow them..much cheaper. I do not know what a bag of scratch costs..so perhaps the later statement is not true.
