She may be stumbling because she is weak. How long were you gone? Did you leave someone to take care of them (change bedding, water, food daily, maintain appropriate temperature, and check their health)? Don't hold her often as it may stress her out more. Keep her in a quiet, dark place and continue to check on her. Make sure it isn't too hot or too cold and that she has the ability to move away from the heat. Give her the regular feed (you could add some water to make it a mash, but that will have to be replaced at least once a day). Make sure the bedding is clean. I would agree with getting her to drink some probiotic water. That will help boost her strength. Keep us updated!
