I have a rooster flock living on the farm. We only stay on the farm occasionally, so the roosters are by themselves often. The longest is about a few hours short of a week.
We have 3-4 feed stations for 4 of them, 2-3 water places, using strong steel mesh on the inside and timber on the outside for their coop with steel mesh skirt to prevent digging.
We also put a smaller chicken coop for them to sleep in and dog kennel inside for the one lower on the peck order to hide.
With 54 birds, you need a gigantic coop, ideally separated in a few areas. Personally I would put in at least 10 feeding stations and at least as many water places to give bullied birds some chance to eat and drink.
I have roosters, that makes things easier. There are other questions that you have to ask yourself. What are you going to do with eggs? What if one of your hens start having reproductive issues?
If you must, you can start with a system that you think could work, then improve upon that, make the period between you visits longer and longer while fixing on the issues that you do not foresee as you go.
