I have two beautiful pullets I brought home 4 weeks ago. Within 2 days, there was clear discharge from the nares. By the end of the first week, I was sure I was going to lose the coronation sussex. She was making gurgling noises, discharge from nares and lying down with her eyes closed. The RIR had the discharge and sneezing but was otherwise ok. I went back to the breeder, who gave me tetracycline antibiotics (a teaspoon per 4 litres of water), which helped the sussex amazingly the first day - she was back up and about. They were on the antibiotics two weeks until it ran out. They have been off it nearly a week and the symptoms have returned. They are both bright eyed and active and eating, but the sussex has the gurgling noise when she breathes and the RIR has the sniffles and sneezes.
They have been wormed with a wormer that kills gapeworm four weeks ago and are vaccinated against Mareks Disease, Fowl Pox, Coryza & Mycoplasma.
They are gorgeous girls and I would hate to see anything happen to them. They don't seem terribly ill and are out happily free ranging, but I am worried it has been so long and I can't get on top of this. Any help would be very much appreciated!!
