I've been filling the feeder to the top, and the silly hens are treating this like a wonderful version of Costco samples, meandering through, tossing out much of what they need in searching for their favorites. I was wasting soooooo much feed, just trashed. Not fun with the expense of feed now. So, now I put in only as much as I know they will eat in the morning, early afternoon, then refill with just enough for them to eat until the end of the day. I provide healthy treats durning the day also, fruits and veggies they like. What I'm discovering is that they are actually eatting less, foraging more for fresh bugs. I am careful to make sure that their feeder is never empty of course. Now they pick through, but without more feed sifting down, they also eat the rest of the food, just desert first!
