Hi All! In reading through other threads and receiving advise from some here (THANK YOU!) I wormed my chickens today, with invermectin paste. Everything went smoothly as all of my hens are really tame and I can pick them up and hand feed them the wormer hidden in a hole in a piece of cheese. My roo, on the other hand was hen raised and isn't aggressive yet, but not one I can just pick up. So, I got him by himself and handed him the treat. I was so relieved when he took it ...and then I'll be darned if that bugger didn't call over his favorite hen and feed it to her!!! So, I did finally manage to get him his dose, but am worried about the hen. Anyone have any experience with a double dose? Anything I can do? Anything I should look for? I know which hen it is if that helps at all, she is a BR and a good sized bird, 3 1/2 years old. Thanks again!
