Worked with a pair at an aviary. Scary cranes! Really, our sandhills were sweet, but these guys did their best to peck your brain out through your eye socket. Just be aware that they can be dangerous when mature. Building a shift door and pen to shift them over to while cleaning isn't a bad idea. Ours had a dry pelleted Mazuri diet along with enrichment food items such as meal worms, greens, etc. Mice and I think chicks were part of their main diet on rotation. They need high pen walls if you want to keep them in a particular area, even when clipped or pinioned. The larger the pen you can give cranes, the better. They are active birds. If you build a shift pen, you can shift them inside for the winter. I can't remember what our lock in temps were for them. People love the look of them, and I love their calls.
