Hi all. We are buying two bonded Holland Lop sisters and I plan on building an outdoor hutch. It will stay under our sun porch, an open area about 5 ft high with good air flow, and hopefully something we can carry into the garage during extreme temperatures. We're keeping the bunnies outside because of allergies and our dog that likes to chase little critters. There will be a small fenced-in area in the yard for supervised play during the day, and we will bring them inside as much as possible also. We will possibly have a smaller indoor cage for when it's necessary. Advice on the hutch? I've read lots of info on wire flooring. Considering doing a two story hutch with the top being solid wood flooring and the bottom being wire? The lady selling the bunnies recommended having both types of floor but I'm not sure why. How high should their fence be? These are itty bitty girls so I can't imagine they jump very high. We have owned numerous pets with much success, but we are bunny rookies. Feel free to give advice, encouragement, and/or tell us we're idiots. Thanks!
