I hope someone can help! We have had or Arucanna for 5 weeks. Bought we 3 other S of different varieties. They have all thrived despite out 2 much older chickens. Lola has remained smaller and a bit of a loner. We noticed she was not putting on week and this week she was attacked by one of the older hens. We have put antibacterial powder on it and now she is kept in doors until better She's Been unsteady on her legs but this morning can't stand and when she tries she flaps which just pushes her backwards. Can anyone advise?
