I have searched and read so many threads (old and new) about tossing the eggs after using the stuff. On the package it says you can process the bird after 3 or 4 days of ending treatment. why would you have to toss eggs for longer than that?? some say 14 days, some say 21. I needed to use this stuff because I lost a banty girl with a huge swollen eye and felt it was best to go ahead and medicate the entire flock. no other birds have had this problem. but with the wet weather we were having, they all kind of had some sneezing and coughing. but after treatment, all seems fine and they don't seem to be coughing as before. with that said. 2/3rds of my flock is reaching laying age, which means I am going to start getting LOTS of eggs each day. and to toss that many will be heart breaking. do I really have to wait 2 to 3 weeks?
