Hi! I have 8 chickens in a moveable chicken tracker over nice grass. I am tired of watching the rodents eat the chicken's grain each night. I would like to hand feed, mid-day, to reduce waste. Ideally, the food tray would be empty by evening. I could either toss the food on the ground. (It is a meal, so this may not be ideal). Or, I can put it in their feeder each day. But, what I would like to know is...how much grain does one, young, layer chicken need, if they have access to new grass each day? Thank you!
