I have a small coop about 5'x2' how many quail can I house comfortable in that amount of space? Also the bottom of it does not have wire, it's a wooden bottom that has shavings in it at the moment. Is wire really necessary? I had used it as a brooder for chicks. What protocol should I follow to ensure it's clean enough since I did have chickens in it? Also, it's located in my chicken's run...behind their garden-shed-turned-coop. It's 4' off the ground though so they will not have direct access to my chickens. Will this be an issue? Thank you in for any help you can give me!
