Where can one get fenbenzadole wormer? I've been treating my rooster that may or may not have this. We Took him to the vet this dec26 after we Noticed his crow first to sound horse and then the next morning(on x-mas day) his breathing labored. His comb and Wattles were extremely discolored from lack of oxygen. The vet gave him a steroid shot and a shot of ivermectin. ( with a follow up dosage 3 days later). We've been giving him ceftiflex for the past 4 days till we discovered particulars floating in the solution from a possible heat exposure. Now he is receiving SMZTMP. 1cc orally 2x's a day. His color is better. He doesn't have the rattle as much. Still not to interested in food. I hand feed what I can get down him. And water him as we'll. we're into our 5th day now. If he has gapeworm, can he still be treated for it. We have a flock of 40 chickens. No one else shows signs of infection. Thanks.
