Here at H&H Poultry we quarantine our birds. Why? You don’t know if the chicken(s) has some sort of sickness. Keep them separated from the rest. Keep a close eye and look for any sneezing, coughing, nasal discharge, bubbles in the eye, leg mites, and mites. If they do have those symptoms keep them separated from your flock until it has been treated.
Gwen the Guinea Hen has an injury so we separated her from the rest of the flock.
