My meaties are about 7 weeks old, Colored Broilers. They are currently free ranging and mixed in with my flock. I noticed some sneezing from them a couple of weeks ago, but I didn't hear a lot so I figured it was because they were eating the crumbles so quickly. Now several of them have puffy eyes, and my usual treatment isn't working so far. I use Vetrx topically for my other birds that have come down with this issue, and it had always worked for them. I am continuing to treat them. If I cannot rid them of this, are they still safe to eat? Their symptoms are only the puffyness around the eyes, and maybe a little lethargic, no or infrequent sneezing. But it's hard to tell, they all just eat and lay around! I would appreciate any help, thanks!
