Yes, I like my feed available free choice as much as they want also. But since I live in the Pacific Northwest, we might get just as many rainy days as sunny. So it was pertinent to have my run covered from the get. The front half still gets wet during blowing wind, but I set my feed just out of the usual reach of the weather.It really depends; there are many ways which may or may not work for you and your situation. I provide feed inside the coop only to keep the food dry and out of the weather, and I keep the water outside, which forces them to get some exercise running between the two. However, if you wish to feed outside, it is possible to build or buy weather proof feeders. My SO built one for his parents for their ducks who live outside 24/7.
Some people prefer to feed only a certain amount at a time to help reduce the presence of mice and other feed scavengers. Others, like me, prefer to make food available all day (for convenience's sake). It really just depends on what works best for you and your flock
