Does exposure to sun make them eat more?

So yesterday I was cleaning the brooder and since it was really warm and sunny outside, I decided to put my 3-4 week old chicks in the run area of my egglu cube while I cleaned. The cube will be their home when they are old enough to go outside. I have 9 chicks and they had never been outside. They were having a great time eating grass and playing keep away with tasty treats. They were outside for maybe 30 minutes. Once I brought them inside and put them in their nice clean brooder, they ate an entire feeder full of food in a matter of 4 hours!!!!! The feeder usually lasts a day and a morning! Do you think the sun increases their appetite?

The increased activity caused their appetite. And they should be feathered in enough at this point to start getting them adjusted to life outside. My chicks are usually off heat completely and outside permanently by that age.
