Semi-related... I give my hens a snack in the afternoon. They don't eat the fine bits of dust that fall to the bottom of their feed bowls. I save that to make their afternoon mash snack. Very little of their feed gets wasted.
Reasons for having snack time? It's a chance for me to visit my chickens, sit awhile, interact with them, watch them. I also give them kitchen scraps along with the mash for variety; not to replace their food, just to be a treat. Those can also be tailored to the temperature. Refrigerated melon guts with seeds are a way for them to get more water and eat something cold.
This is great on those stinking hot days we've been having. A nice cool treat on a hot day.Piggybacking, offering wet mash with cool water when its hot out has some benefits in helping to mitigate heat and preventing gorging - since the increased volume slows their consumption some.
I do this in the cold months. A nice warm treat on a cold day.And you can use warm water in cold weather, too.
If their water source freezes, they get thirsty and quit eating, so nice wet mash lets them fill up on both food and water quickly, before it all freezes again.
