Example of how I have been using these supplements: (They always have Purina Flock Raiser available in their feeder)
This is for 13 chickens:
This morning I threw a 6oz yogurt container of cracked corn for additional entertainment on the 5 degree day through out the run and coop.
Mid morning I served another 6oz yogurt container with a mix of pumpkin meat, peanut butter, fish oil, crushed garlic and red peppers
Before Bed they will get another 6oz container of cracked corn.
I will alternate the morning cracked corn with Game fish chow (30% protein). every other day. Other days they don't get a mid day snack
