A Question concerning Ethology

Hello Backyard Chicken Members! As a potentially new Chicken owner I'm here to make sure I get it right from the start. I've actually worked at barns that have backyard chickens so to speak practically my whole life growing up in a small town and going to a welder farm school where we took on barn chores. however I've never done this myself and I have a few questions. In addition to my interest in home stead farming I'm an aspiring progressive positive reinforcement dog trainer, and plan to make this my new career path. now idk if you've heard but dog trainers have been using chickens to hone there mechanical skills coordination and timing in training any animal (yes including us!). So as a trainer the welfare of the animal is of the utmost important to myself. This leads to my first question my family is having a chicken coop made my some local farmer and builder. My father is concerned with cleanliness and suggested to the builder putting in an epoxy flooring for efficient cleaning. my concern is in the ethology of our chickens, will the texture of the epoxy floor be of concern for their feet, legs and footing so to speak. of course we will put hay/shavings or the suggested bedding of choice among all you experts. Any feedback is MUCH Appreciated! thanks sooo much and thanks for having me here I cant wait to learn from you all.
