I now have 3 chicks with a leg problems. They're almost 8 wks old. Started with a limp and balance off. Now when walking they drag it or when laying down it's straight out behind them. The first to show signs ended up with both legs behind her and rolled from side to side. Brought her in for TLC but even though she eat mash & corn still lost weight. Lost her but now have 2 more just starting with the weak leg. They are free range and mixed breed bannies.
