Hi I am new to posting on BYC but have been reading the forum for 2 years. I have a 28 week old pullet named Lizzie who just today started stumbling around and walking very unsettling crisscrossing her legs as she's walking. She sits on her haunches a lot and is unable to stand on one leg. She is eating and drinking and running around she's just unsteady. I've started to treat her with vitamin b12 and selenium. Any suggestions on what it could be and what else I can do for her. She had a sister who passed away at 8 weeks of age from similar conditions in the end she had full torcullis and couldn't be remedied after a week of intensive treatment of vitamins and minerals and Tube feeding. I really hope not to have to go through this again with her sister Lizzie. Any advice and help you guys can offer would be much appreciated.
