I realize they're not as active. But I'm concerned at how little my girls are eating. Normally, I refill their feeder every 3 days. It's been 6 days and it's still half full. ?? They happily eat greens and scratch I throw in the run. I looked at the pellets and smelled them; they don't seem spoiled. Is it just normal for them to be eating less? All seem to be laying fine and behavior is typical. Thanks.
