I have water and food both places. I put their smaller brooder feeder and waterer inside the coop and regular size feeder and 3 gallon waterer outside in run. Regular size feeder is hanging underneath the coop/henhouse to protect it from rain and seems to be working fine. The chickens use both depending on weather, bad weather, they stay inside, nice days they run back and forth, eat and drink in both areas. My run has a roof and hardware cloth/wire is buried about a foot deep at the bottom so hopefully, I will not have problems with rodents digging into the area to get at the feed. If your feeder can hang on a chain or be hung from a wall and thus, off the ground, that is supposed to help with the rodents, too.
