I have 4 lovely ladies but one of them has been sneezing quite often in the past month (all other ladies are fine). There is no fluid discharge anywhere of any sort and other than sneezing and weezy breathing she's acting like a normal chicken. My questions are: 1. Should I treat her with Terramycin or Tylan 50? 2. Does she need to be quarantined or can the other healthy chickens drink the medicated water as well? Right now ALL ladies are getting 1 tablespoon of raw apple cider vinegar in their 1 gallon water feeder (plastic). They also get yogurt and diced garlic once every few weeks. Please help.
