Welcome!
Everyone has different philosophies on this and different setups and situations. If your current setup is working for you, don't fix what isn't broken
Me personally I have 3 feeders, 1 in the coop and 2 in the run. I have that many 'cause at the time I got the chicks I had 2 older birds including one who was mildly aggressive and definitely food aggressive towards other birds so I wanted to make sure she couldn't keep the the chicks from eating. Unfortunately both of the older ones died due to dogs and I assume random heart attack but I kept the same system as more feeders means less need to compete. I also have 3 waterers, 2 foot baths and a kiddie pool that I keep shallowly filled 'cause it's very hot here
Whatever you decide to do just make sure you have 2 of each to prevent resource guarding
