My seabright banty roo has gape worm. Every post I read is different. First I read to use fenbendazole paste now I'm reading to use Ivermectin! I've treated for 2 days with fenbendazole paste. He does not seem to be getting any better and I am seriously thinking I will lose him soon. What is the right thing to use and when do you typically see results!! I am desperate! Can I dose him with the Ivermectin if that's what he needs? HELP!
