My girl Autumn was on the nest for 16 days(I had her locked in a medium dog kennel). 4 days ago I opened the door and she came off the nest. I suspect she couldn't get back to her nest. She has lost a lot of weight. Her legs aren't stiff. She can't stand very long and she wobbles/limps when she does walk. She has a good appitite and drinks well. Poo is normal. Feet aren't swollen. Any Ideas?
