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!
