My one year old Buff Silkie hen just started Wheezing and seems to have teary eyes, but then again her head poof is so big its hard to see them. Should I treat her with Duramycin-10 or Tylan and what ammounts for a one gallon waterer? She eats fine and drinks so I don't think its serious. I handle the birds every day so I would have noticed it any sooner. I'm also calling my vet but may not be able to get a hold of him for a few hours. They can be slow for phone calls and rarely treat chickens. Thank you veeeerrry much!! I really love my girls and hate for them to not be feeling good!!!!
