My silkie hen sneezes constantly all day and night for well over a month now. I have had her for 4 mths was told she was a yr old. She stopped laying 2 mths ago and started sneezing a mth ago. No runny nose, no watery runny eyes. Normal poo, eats drinks and acts normal. My other chicks at 3 mths, penned with the silkie, sneeze sometimes with no other symptoms either. I have done the acv/garlic. The basil and other herbs, the poulvite. It doesn't seem to make it stop. Shavings in coop. A wk ago one chick coughed but hasnt since, today another coughed. Chicks are all just over 3mths. I am freakin out. I am a newbie but I love my birds and spend a lot of time with them. It has been raining a lot wettest summer yet. Whats wrong with my babies?
