welcome to Pigeon Basics rhyseian , we hope you enjoy the site
I would have boxes so can motivate the ybs and have two sections so can motivate them and split the sexes as how to fly them all depends what you want to achieve and what type of birds you have but as your starting fresh with ybs you can either fly natural or darkness , theres pros and cons for both systems , but it all boils down to type of birds and what your wanting to achieve be it sprint or distance racing
