My runner babies are getting big. Right now they're in a pen out in the pasture during the day but at night they go back into their rubbermaid box which they're seriously outgrowing. I need to get them a house built but have some questions. 1. How big does it need to be for 10 runners? 2. Should it have a floor? They're so incredibly messy I thought it'd be a lot simpler to just have a dirt floor. But what about snakes? The house will be in a run with electric fence on the outside. How bad do I need to worry about predators compared to chickens? 3. I'm guessing they need to be locked in at night like my chickens and let out during the day. Do I have to keep food and water in the house or can I leave it outside and just give them a nipple waterer inside? 4. I was going to put one of those tough black rubber bowls in for them to swim in. Is 15 gallons big enough? Or should I just go ahead and get one of those pond things from Lowes? Any advice would be greatly appreciated! Thanks!
