I have a young silkie pullet (6 months) who seems to be sneezing all the time. She's been doing this for a couple of months. There is no eye or nasal discharge & no smell of sickness. Her appetite & poop are normal. I thought maybe is was a response to the fires locally & the ash in the air but it hasn't changed as the air quality has improved. None of the other chickens are doing this or show signs of any sickness. I am stumped. Any suggestions? Should I try VetRx on her comb & in her throat? Any thoughts on colloidal silver? Or should I go directly to antibiotics (Tylan or something else)? Thanks.
