Hello all. I've been sucked into the craze of chickens. I grew up with them and my parents still have some but I want my own. I will be receiving my first 2 polish hens in May and can't wait. So my first questions is placing the coop. I am connecting a rabbit hutch to a playhouse and using both for inside protection and the rabbit hutch for extra outside space when I can't let them in yard. But what my problem is the outside area will be on pea gravel. Do I need to move this and put sand down? Any help is very welcome.
