I personally think real food is better than rations, my birds diet is about 1/3 ration and the rest is freed range and anything else I feed them throughout the day, my flock is quite robust and healthy, I pursue a different way of feeding, I keep heritage breeds, sex links don't do well with this type of feeding, they seem to need a higher protein ration because of the amount of eggs they lay. So take what you learn and apply what you think than see how your chickens do, if it's working for you than do it.I am curious about that 10% number. I guess it depends on what would be considered a treat. Are fresh fruits and veggies considered treats?.If so then I am definitely guilty. Those things I have been feeding daily in some quantity. I use hanging feeders 1-12# and 1-30# which I never put more than a couple inches of feed in at a time. I check it a couple times a day and usually put about 16 cups of food out in the morning and sometimes in the evening. The 2 feeders service 24 birds ranging from 18-22 weeks. I have never really seen it empty but I know their intake is increasing as they grow and the evenings are becoming cooler so they are happier in the morning.
I know this because I just got feed today. The bag they just finished lasted 2 weeks, the bag prior to that lasted 3 weeks.
That means that each bird is averaging 1/2 a pound of feed a week. Does that sound about right?
Everyone is well feathered and appear to be thriving and as I said I can see the effect the summer has had as far as perhaps a little slower to grow and lay. 110+.is stressful on me so I am sure it was slowing them some. I use the fresh stuff in quantities to help stimulate their appetites in the mornings and usually cold fruit to help them cool off in the late afternoon to again get them going before they bed down. Mornings are either greens or maybe corn on Tue coz if it is cheap. You break 4 ears of corn into 3 pieces each for 2 dozen birds and it is just enough to whet their appetites.
1 large head of lettuce or cabbage shredded or a couple heads of romaine shredded doesn't last long and after a short preen the next thing you see is everyone working the feeders.
Afternoons are usually fruit. Again 12oz of blueberries, or a pound or so of grapes doesn't last long either. The fruit and raw sunflower seeds enable me to do a good daily inspection and actually probably allows me to observe what the actual pecking order is within the group.
So are greens considered treats or a form of forage.
