My boyfriend has a 6ish month old chicken. It is his first chicken and he wants to do what is best for her. She is living in his living room. Her cage was a rabbit hutch but she pecked a hole in the floor and was pushing her bedding through it and the floor was impossible to keep clean. Now she is temporarily in a wire cage with a mesh floor so her droppings will fall thru to the catch pan. She is allowed to roam around the living room and kitchen when he is home during the day so she does get a lot of exercise, though she has never been outside. The mess and the smell are overwhelming. She is pooping in her water dish and tipping it over so that is cleaned and refilled every few hours. He does not want to give her up but will if living inside is not in her best interest. He is a contractor and can build her an indoor coop, he just needs advise on the design. One that can be easily kept clean and that will keep a chicken happy. Also, how do we reduce the smell. I don't think it is healthy.
