In driving around the county I've noticed the blue heads and dowager walks of emus in people pastures. I'm new to emu care, we have one on our property. And this morning when she came up for her breakfast she was crouching and shivering. Her feathers frosted. If I close her in the barn, I think she'd revolt. And normally she rests under a lone tree as sunset. Tell me emu people - is there anything we should do to protect her?
