She was born around Easter of this year (2010). She's a cornish-rock hen. She only gets up to walk when she absolutely has too. she seems to be favoring her left foot. We had another chick in the same flock act the same way and it ended up dying app. 2 weeks later. She stills eats and drinks though. It doesn't seem like she has a disease but since the situation seems to be repeating itself, im concerned for the rest of the flock. Any advice will be appreciated.
